Minister of Land and Resources recently held China International mining Conference, said China is committed to scientific development, continue to adhere to save low resources consumption, little environmental pollution and the new road to industrialization. 'scientific development, promote green mining' is a new path of industrialization in China mineral resources in the field of concrete embodiment. Here, the green mining industry has become the most eye-catching words, the reason for it visible, because it is China's economic development, because it is in line with the direction that mining industry calls for the requirements of energy conservation advocacy and environmental protection development.

The so-called 'green mining' refers to the disturbance in the mine environment is less than the premise of the capacity of the regional environment to achieve optimal exploitation of mineral resources and the environment are minimized. Implementation of green mining industry there are three stages: First, the regional environment through the development of capacity or former capacity evaluation and mine environmental assessment and disturbance, the establishment of environmental evaluation index system and technical standards, to develop green mining plan; but through technological innovation, optimize Process, to achieve mining, dressing, smelting and refining process, a small disturbance, no poison and less pollution; Third, through the mining environmental management and ecological restoration, to achieve minimum environmental disturbance and ecological reconstruction optimization. We say that the development of green mining is the voice of the times, China's economic development, it is not groundless, but evidence-based. Over the years, our economy has been growing rapidly though, but we also paid a high price, called a lot of fees. Relevant data show that the country due to ground subsidence due to mining to 180 locations with more than 1,600 pit collapse, subsidence area of over 1150 square kilometers. The collapse of the national mining subsidence disaster occurred nearly 40 cities, causing serious damage to the 25 annual ground subsidence due to mining, the loss occurred up to 4 billion. The mining, ore mining 6 billion tons per year the amount of disturbance of the Earth's environment, induced the mountain crack, collapse, landslide, debris flow, earthquake and other geological disasters. These figures are shocking, but in order to change this situation, to promote green mining industry is the best way.

China's hydraulic mining machinery industry and the world advanced countries there is a gap, and the gap is our great progress space, in order to be able to reach the world advanced level, only recognize the difference, the gap from place to start, and constantly improve their standards in order to continuously improve our ability of hydraulic mining machinery. Let us first analyse our country and the advanced countries in the world in hydraulic mining machinery industry gaps.

Hydraulic network of excellence senior consultant hydraulic Li Gong from the current point of view, the domestic mining industry science and technology foundation is thick, and the field of the mining machinery has been change a technology with the market as a way to improve the level of product technology is not phase, and to face the foreign competitors, especially the foreign competitors in the domestic investment and set up factories in the grim situation. Therefore, the domestic mining machinery enterprise innovation consciousness forced excitation.

Domestic major mining machinery R & D and exporters in Shenzhen city of God extension mechanical and electrical equipment limited, enterprises in the face of domestic and foreign innovation competition of enterprises, after years of rapid adjustment, now Shanghai state of the world has been established, complement and perfect the advantage domain application research and development base, launched to crusher, milling machine and system sand machine as the main products, manufacturing process and process technology application research. Shanghai world Bang after the pioneering and innovative ways, practice, research and development of new products, to meet the mineral resources of mining machinery made more specific, more explicit content of innovation, in recent years the company's R & D results: tracked mobile crusher station, a mobile mobile crusher station, PFW European version of deep cavity hydraulic crusher, JC the European version of jaw crusher, cone crusher, CS HPC hydraulic cone crusher, sand making machine, the new VSI VSI5X centrifugal impact crusher, V.W high grade stone shaping machine, MTW Euro trapezium mill, LM large vertical milling machine, SCM superfine milling machines and other equipment are energy saving, water saving type, comprehensive utilization, environmental protection of mining machinery products, and can give the operators to create a safe and comfortable work environment.

So, our country and international developed country the main reason of difference of existence or technical level. China in the innovation and international developed country manufacturing level is still a gap in the domestic challenges, so great. Domestic and foreign mining machinery gaps exist for many reasons, including market demand differences are caused by a gap between the objective reasons, due to the international market for excellent mining machinery manufacturers focus areas in Europe and the United States, where large-scale basic construction stage has in the past, the market for aggregate demand is not much, and environmental protection requirements are high, certainly will forms gravel field height focus on large-scale production to achieve environmental protection, they required mining machinery specifications, strong maneuverability, high automation process think. To meet the market demand for the development of the mining machinery and domestic product is not the same as, as we are at the large scale infrastructure throughout the period, the demand for mineral resources mineral resources increase, investment caused by heat, blossom everywhere mines are often small in scale, but started fast, less investment, the market demand so crudely made, technology level is low, energy consumption high, serious environmental pollution products have entered, but these devices are often only at low prices to capture the market, so with the international advanced level difference.

Belt conveyor is a kind of friction drive by the continuous mode transportation machinery materials. Application of it, the material can be in a transmission line, from the initial material to the final point of discharge is formed between a material conveying process. It not only can be broken loose material conveying, can also be carried into pieces of goods transportation. In addition to the pure material handling, but also with various industrial enterprise production process in process requirements are matched, formation of rhythmic flow transport line. The belt conveyor is widely used in modern industrial enterprises.

In mine underground tunnel, mine transportation system on the ground, open pit mining field and ore dressing plant, widely used in belt conveyor. It is used for transport or incline transportation. Common belt conveyor by the conveyor belt, roller, roller and a driving, braking, tensioning, modification, loading, unloading, to cleaning device.

Belt conveyor technology:

The first is the reliable operation of belt conveyor. In many continuous operation of the important production units, such as power plant of the transportation of coal, iron and steel plant cement plant and bulk material conveying, and port handling of ships were using belt conveyor. In these occasions such as shutdown, the loss is huge. When necessary, belt conveyor can be a class with a class of continuous work.

Belt type conveyer power consumption is low. Due to the material and the conveyor belt with almost no relative movement, not only make small running resistance (about the scraper conveyer 1 / 3-1 / 5), but also to the load of attrition and fragmentation are small, high productivity. These are beneficial to reduce the production cost.

Belt conveyor line adaptable and flexible. The length of the line is set according to the need. The short several meters long, can reach more than 10km. Can be installed in a small tunnel, also can be mounted on the ground traffic chaos and danger area in the sky.

According to the process requirements, belt conveyor can be very flexible to from one or more points by feeding. Can also provide more or sections of unloading. When simultaneously at several points to the conveyor belt material (such as coal washery coal bunker under the conveyor belt conveyor) or along the length direction on either through uniform feeding device to feed conveyor, belt conveyor has become a major transportation route.

Belt conveyor in coal storage yard stockpile below the roadway reclaimer, when needed, but also the different material for mixing pile. The material can be simply from the conveyor head unloading, also available through plough type unloader or mobile unloading vehicle in the length direction of the conveyer belt with any point discharge.

Screw conveyor or auger, suitable for granular or powdered material conveyor of the horizontal, inclined conveyor, vertical conveyor and other forms of. Transmission distance varies according to deformity, usually from 2 meters to 70 meters.

Principle of transport: rotation of the auger blade passage for the material screw conveyor. The material and the spiral conveyor leaf rotation force is the material of its own weight and screw conveyor casing material friction resistance.

Structural features: screw conveyor rotating shaft is welded with a helical blade, blade face delivery of materials according to different entities of type, belt type, leaf type and other types. The spiral shaft of the spiral conveyer in the direction of the material movement of the terminal with the thrust bearing with material to spiral axial force, the captain a long time, should be added the middle suspended bearing.

Double screw conveyor is two are respectively welded with the rotation of the rotary blade shaft of screw conveyor. Bluntly, is two screw conveyor are organically combined together, form a spiral conveyer.

Screw conveyor rotation axis of rotation to, determines the material conveying direction, but generally screw conveyor in the design are designed according to individual carrier rotating blades. When the reverse transmission, can greatly reduce the conveyor life.

Bucket elevator: using uniform is fixedly connected to the endless traction member on a series of vertical lifting material hopper, the continuous conveying machinery.

Bucket type lifting machine has large conveying capacity, high lifting height, stable and reliable operation, long life advantages, its main properties and parameters with the JB392685 'vertical bucket type lifting machine' (the standard equivalent with reference to the international standards and advanced foreign standards), traction chain with MT3680 'mining high strength ring chain', the lifting machine for conveying powdery, granular and small block of wear resistance and wear resistance of small material, such as: coal, cement, stone, sand, clay, minerals, due to traction hoist is a circular chain, thus allowing delivery of high temperature of the material (the material temperature not exceeding 250 degrees Celsius). General transport height up to 40 meters.

Mountain mechanical applications and infrastructure are closely related, the future will have a huge market. However, industry believes that the overall mining machinery in China with the international advanced level compared to 15 to 20 years behind most sources of technology products for the mid-1980s from abroad. Domestic market share of mining machinery products in the market less than 80% in the imported products are mostly large, fine, sharp and strong sets of products, such as coal mining, large efficient separation equipment, crushing and grinding equipment, all joint cross-section boring machine and other products.

Mining machinery industry's technological base is not strong, reform and opening up, has been in the field of mining machinery market for technology to improve product technology level as the main way. Throughout the world the development of mechanical design process, mainly stand-alone single product design to product design to process equipment design process evolution. China's general mining machinery manufacturing completed only stand-alone product design and manufacturing equipment used in the design process to do by a professional institute, the craft of stand-alone product requirements proposed by the professional design institutes and assist manufacturers to complete, which resulted in equipment manufacturer and device disconnect between departments. Experts believe that in the current mining machinery manufacturing industry, the business process design is relatively weak in the case, good condition, except in their own areas of expertise into the role of organizational strength as soon as possible, should be taken with foreign and domestic companies to establish various forms of professional institute joint, including the formation of groups, unions, the introduction of technology, the introduction of qualified personnel and other measures to fight in a joint project on the design approach, the first intervention and then to improve and achieve win-win situation.

In addition, experts suggest that as quickly as possible, to supplement and improve the application of the advantages of professional laboratory for product, manufacturing process and process technology research. Not applied technical research data and databases, you can not convince customers to use the company's products and technology, not to mention the truly innovative application of technology.

Based on the actual characteristics of the situation in the mining machinery, oil is very strict on the requirements, as follows:

First: As the volume of mining machinery and its fuel tank volume are relatively small, so it is easy to appear the work of a high oil temperature, which requires oil to have better oxidation resistance and thermal stability.

Second: Because the gravel mining machinery working environment is very harsh, dust, water was relatively large, oil is vulnerable to the contamination of impurities in the external environment, so the oil must have a good anti-rust and anti- corrosive. Only in this way by the outside world when the oil in the case of adverse environmental impact, its performance will not have significant change.

Third: the working environment of mining machinery and equipment is usually outdoors, so the work environment affected by temperature changes, especially the large temperature difference between summer and winter, day and night temperature difference in some areas is relatively large, so the oil viscosity must be less affected by temperature, this area requires high temperature, it will not lead to too low viscosity, but not the line as a lubricant, the other is to avoid the temperature is low, a result of low oil viscosity Start with the operation difficult.

Fourth: There are some easy fire or explosion mining machinery, of course, requires a certain degree of anti-flammable oil, mineral oil can not be used to fuel for lubrication.

Fifth: The last is certainly better than the seal lubricant to prevent seal damage and impact on the effect of lubricating oil. Lead to some unnecessary risk.

As people know, mining industry is treated as the most difficult and dangerous economic activities.

It's the products of this activity that allow society to function the way it does today. One can only imagine what life would be like without the products of mining. Daily activities would be hindered without the production of natural minerals and coal; not to mention its effects on economic activity. Luxuries like jewelry also come as a result of the mining of precious metals.

Methods have developed greatly over the centuries. Matter of fact, major developments happen on a daily basis. New sciences and technologies allow the industry to grow and provide more for the world. Many people are unaware, however, of the methods and procedures that go into the mining process.

There are two common excavation techniques used today: surface and sub-surface or underground mining. The more common of the two is surface mining seeing as it produces a majority of the world's minerals.

Surface mining, as its name might suggest, is the easier of the two. The technique involves the removal of material that can be found on the surface such as vegetation or dirt. If necessary, miners dig into the bedrock to reach the deposits they are aiming for. This technique employs the use of one of five further forms of surface mining. These include strip, open-pit, mountaintop removal, dredging, and high wall mining.

Sub-surface mining, on the other hand, is the exact opposite of surface mining. This technique involves the digging of tunnels deep into the earth's surface to reach the deposit. The products of this type of process are then brought out through the tunnels and shafts created. Unlike surface mining, which is classified into five forms, sub-surface mining is classified by the type of access shaft used to extract whatever mineral needs extraction.

Advancements in mining equipment such as green light laser technology have made it much easier for miners to do their work. Most people are unaware that laser technology plays a big role in the success of any mining operation. Red light lasers used to be the standard, but green light lasers are starting to become more widely used. This is because green light is apparently much stronger than the red light, and is also visible under direct sunlight.

People tend to confuse the petroleum industry as being part of the mining industry, but this is not the case. It's easy to confuse the two, considering that the retrieval of petroleum involves the gathering of a product that is below the surface. Petroleum, however, is not mined like other minerals. This is because petroleum is in a liquid state; for it to be retrieved, it needs to be pumped out.

In recent days,the temperature has dropped suddenly. Thus the situation of power shortage eased in China's western Guangxi Zhuang Autonomous Region. Experts suggest that we should adopt the strategy of protracted war to handle with this situation. Guangxi needs to change the industrial structure which is based on high energy consumption industries.

Since this summer,the supply of power is not enough due to dry weather. The power contradiction in Guangxi appeared a severe power shortage in a red warning signal, the maximum demand of electricity power shortage about 30%.

Lin Boqiang said that we should increase the capacity of installed machinery and improve the configuration to deal with the power shortage. We should take the situation of long-term drought into account and increase capacity of installed machinery. According to the statistics of Guangxi Power Grid,the total power capacity is 25.33 million kilowatts,14.94 million kilowatts hydropower, thermal power 10.39 million kilowatts.

Cement and other high energy-consumption industries are major consumers of electricity in Guangxi.The commission of industrial development and information technology show that total electricity consumption is 73.341 billion kw/h from January to August.Among them, the first industrial power is 1.353 billion kw/h; second industrial power is 54.553 billion kw/h; tertiary industry is 6.038 billion kw/h.The proportion of aluminum smelting,iron alloy smelting consumption is high and the power consumption is rising in the industrial electricity.

Strengthen reliable performance: Even open coal mine stripping operations are easily collapse, it put forward higher request to the materials of mining machine, in case of dangerous accidents the driver's safety can be guaranteed. It should be taken into consideration in the machine functions, such as it can be equipped with a similar small hammer to the bus which can be used to break glass in dangerous conditions. In addition, mine mining machinery products closure and escape performance should be improved.

To distinguish whether the large-scale mining machine crash to other vehicles, changing the mechanical cab is necessary, it can help to reduce the blind range of the driver and will help improve the mining construction safety.

At present, in large mining, small cars must insert a red flag to prevent rolled by large mining equipments. The blind range of some large mining equipments can reach 30 meters, small vehicle drivers must be careful, especially in the pass avoiding to close to large-scale mining equipments.

A remarkable characteristic of mine construction is its danger, even in the smooth road. How to ensure the safety of mining construction, mining machinery, and development is an important direction of the product.

Focusing on energy conservation and environmental protection: Mining machinery products are generally in high intensity work environment, many products are in non-stop mode of operation except during product maintenance time every day. Running more than 20 hours on boot operation is a test for the performance of the product. A customer once said, some manufacturer promise him that the product can be used for six years, however, in a mining field, three years is the maximal utilization period. Customer's request for the product is reliable, the product can to maximize efficiencies in the shortest possible time. For mine which highly dependent on equipment performance of construction environment, product reliability is an important aspect of mine head attention.

To improve safety performance: Mining area is not worry about the number of devices, and in many mines, we can see in the soil to dump truck loaded excavator, often have several cars in the queue which makes the vehicle without full capacity, it causes the waste of resources.

In the mine internal construction, dump truck is one of the largest usage product. Since last year, some Chinese companies marched into mine dump truck field, mining transport equipments as big main development direction are more obvious. It is likely that in several years later, equipments below 30 tons capacity will not be permitted to enter mining construction site.' Chairman of Inner Mongolia ZhunGeErQi kun gold machinery engineering Co., LTD Yu Guojin said. Creating more economic construction in a short period of time is the focus of mine construction . The products are made to improve work efficiency. Users calculation of the economic benefit of mining machinery products is important, the most careful 'durable ' is always the first requirements. In a recent period of time, the reporter has been to Inner Mongolia, Qinghai's to investigate, they discover customer's need of the product has a very distinctive characteristic.

There is a vast range of mining equipment available, dependent on the application for which it is to be used. Underground mining, surface mining and open pit mining all require the initial movement of large quantities of earth. This equipment is similar to that used in large building projects, in the form of dump or haul trucks, diggers or shovels, back hoes and cranes. The extraction of ore requires a different collection of mining apparatus. Ore crushers, explosives, separators and other devices complete the full complement of necessary mining equipment. It is vital to remember that personnel are the fundamental aspect of any mining operation and their safety is paramount. Essential mining equipment must also include safety supplies, such as hard hats, ear defenders and respirators, to prevent employees form injuring themselves (or each other) whilst working in hazardous conditions.

Many criteria need to be considered in selecting the appropriate equipment for a particular mining operation. The most important factors to consider are safety, strength and durability, though cost can be a major aspect.

Heavy duty earth moving equipment can be bought direct from specialist manufacturers who focus on loaders, trucks, drills and scrapers. Other companies offer leased rebuilt / used mining equipment by major manufacturers. Many mining equipment manufacturers make ore extraction equipment. Some specialise in air compressors concentrators and tunnel boring machines, whist others produce conveyors, crushing plants and hoppers. Specialist underground mining equipment manufacturers offer an extensive range of pallet handles, tow tractors, belt drives, radial stackers and power packs. Several manufacturers produce a range of health and safety products. Some specialise in respirators, hearing protection, gas detectors, fall protection devices, hard hats and goggles, while others offer an assortment of specialised flags and lights for use inside mines, along with rescue equipment for both underground and surface mines.

A mining undertaking can often be large and complex. In order to ensure a project progresses efficiently, safely and is completed in a timely fashion, sufficient supplies and equipment must be made constantly available. For speedy service and extensive choice of products, the Internet is an excellent choice for the purchase of mining equipment. Many mining equipment manufacturers and distributors have detailed specifications and photos of their inventory on their websites and there should be few problems in locating the appropriate tools and equipment for any mining project. New equipment can be bought directly from its manufacturer, though it can be a good money saving exercise to peruse the used and / or refurbished equipment offered by many manufacturers. Other firms specialise in the hire of mining equipment and dependent on the available capital, this may be a preferable option to outright purchase.

Just to be clear, in spite of advancements in mining machines, mining is still among the most difficult and hazardous economic activities. It's the products of this activity which allow the world to function the way it does today. One can only picture what life could be like minus the products of mining. Day to day activities gets impeded without the production of natural minerals and coal; let alone its effects on economic activity. Luxuries like jewelry also come due to the mining of precious metals.

Machines have developed greatly over the ages. Matter of fact, major improvements occur every day. New sciences and technologies enable the industry to develop and supply more for the world. Lots of people are unaware, however, of the methods and procedures that go into the mining process.

There are two regularly-used excavation procedures applied today: surface and sub-surface or underground mining. The more widespread of these two is surface mining seeing that it produces a majority of the world's minerals.

Surface mining, as its name may suggest, is the less difficult of the two. The process requires the removal of material that is found on the surface including vegetation or dirt. When necessary, miners dig into the bedrock to reach the deposits they're aiming towards. This technique utilizes the usage of one of five further kinds of surface mining. For instance, strip, open-pit, mountaintop removal, dredging, and high wall mining.

Sub-surface mining, on the other hand, is the exact opposite of surface mining. This system involves the burrowing of tunnels deep into the earth's surface to hit the deposit. The products of this kind of practice are then brought out through the tunnels and shafts created. Unlike surface mining, which is classified into five forms, sub-surface mining is classified by the type of access shaft used to remove whatever mineral needs extraction.

People tend to mistake the petroleum industry as being part of the mining industry, but that isn't the truth. It's easy to confuse the two, considering the retrieval of oil involves the gathering of a product which is beneath the surface. Petroleum, having said that, is not excavated like other mineral deposits. Simply because petroleum is in a liquid state; to retrieve that, it has to be pumped out.

Innovations in mining equipment like green light laser technology have made it easier for miners to do their work. Many people are unaware that laser technology plays a major role in the success of any mining business. Red light lasers were the standard, but green light lasers are starting to become extensively used. This is because green light is apparently much stronger than the red light, and is also visible under direct sunlight.

In Ore crushing plant, gold mining equipment includes Gold ore Crusher , sieving, grinding, washing machine etc. It in the primary mill is loaded for the first time measurement. The mineral mining crusher can the quartz gold rocks in 150 mm or 6-inch pause, then conveyor belt are the crushed ore to the screening plant goes through screens to the size of the mine material handling. Oversized rock is sent via conveyor belts to the secondary crushers.

In Gold ore processing plant, we use devices from pyrite, chalcopyrite, and dignified gold clean. After it mined out, go first through crushing. Crushing rough in it as ore primary Crusher Jaw Crusher is used. Coarse crushing ore with a diameter of more than 10 mm by secondary granulation process go sieve from fine gold powder that gild in this crushing, Symons cone crusher is used. It is loaded into the primary Crusher (Jaw Crusher) for the initial design. The Mineral Crusher can break the rocks of the gold mine in 150 mm or 6 inches (take PE 750 for an example), then conveyor will carry mine crushed plant screening, which manages the gold ore through a sieve vibrating to the size of the material. Oversized stone is sent via conveyor for secondary crushers. Secondary crushing consists of percussion crusher and cone Crusher.

The major stigma associated with the coal industry today is the abandoned or 'orphan' mines of the early coal mining years. These orphan mines are systematically being reclaimed under the Surface Mining Act taxes coal producers at the rate of 35 cents a ton for surface mined coal, 10 cents a ton for lignite mined coal, and 15 cents a ton for underground mined coal. The tax is paid to the government and is used to reclaim the orphaned mines.

More than two-thirds of the underground produced coal is extracted by continuous mining machines in the room and pillar method. The continuous Coal Mining Equipment contains bits of tungsten on a rotating cylinder. The minor continues to face coal breaks, and then it passes to a waiting shuttle car which transports it to the conveyor to be moved to the surface.

It fifty years ago when mining activity the more coal was done manually, underground mines accounted for 96 percent of product coal each year. Today, almost 60 per cent is produced from surface mines. Most of the United States underground mines are located to the East of the Mississippi River, although there are some in the West, especially in Utah and Colorado.

Mining is the process of extracting minerals and geological products from the earth. Miners help collect a lot of elements. These resources are scarce as they are not grown, agriculturally prepared or artificially produced. Precious metals, fossil fuel, gemstones, and gold some of these types of materials. Mining can also help man to get non-renewable power source such as gas, oil, and perhaps water. The duty of miners can be hard and risky. Using reliable mining equipment, the job is much easier now.

People of the old period used the soil for some objectives. A good way to earn a living at the time is through mining. Equipment weren't completely constructed but many people managed to get a lot of gemstones and various forms of metals. They use these types of minerals and elements to generate simple tools for hunting and warfare. Good quality flints within masses of sedimentary rocks were in-demand in many parts of Europe. Folks utilized these flints as weapons in the Stone Age.

Ancient Egyptians were one of the first to successfully pick up minerals from earth. Their particular superior level of civilization made it feasible for them to generate quality mining tools. They excavated malachite and gold. Malachites are green gemstones used for ceramics and also as decorations. The Egyptians began to quarry for other minerals not seen in their soils. They head to Nubia, a part of Africa. There these people utilized metal instruments as mining equipment. That's the time when fire-setting was required to extract gold from ores. This approach involves placing the rock that contain the mineral against another rock, heat it and douse it with water. This was the most efficient mining procedure that period.

The Romans also performed an essential part in the history of mining. These folks were the first ones to use large scale quarrying methods. A good example of this is actually the use of quantities of water to operate simple machinery and remove debris. This is actually the birth of hydraulic mining.

The requirement for metal increased significantly within the 1300s. This was the time when swords, armors, as well as other weapons were in-demand. For that reason, miners searched for more sources of iron and silver. There was additionally an increase in the requirement for coins that induced shortage of silver. Iron, on the other hand, was utilized in developing constructions. With all the high value of these materials, machineries as well as other mining equipment grew to be popular in the market.

These devices and equipment were the mothers of the present mining instruments that we have nowadays. Miners nowadays make use of bulldozers, explosives along with trucks. More complex type of mining resources includes the utilization of green light laser being saw guides and machine alignment. With all these modern-day devices, miners now have a safer and faster process to break down rocks and even carve out hills. All of these materials are created and applied using the principles of engineering.

Today, there are five main mining classes. They are coal, metal ore, non-metallic mineral mining, oil and gas extraction. Oil and gas extraction is among the largest businesses today.

Mining is one of the earliest mechanized industries. Early engineers applied steam power to machines designed to move large amounts of earth quickly and economically. Although the technology improved over the centuries, the fundamental need to move large amounts of earth and rock has not. Images of lone prospectors with a pack mule and pick axe is supplanted by massive machines lifting tons of material and moving earth long distances to processing facilities in a matter of minutes.

Mining machines must be powerful. Breaking rock and coal seams and impacted soil requires vast amounts of horsepower and torque. Modern mining machines, whether hand held or operated by several technicians, are powered by electricity, diesel or gasoline engines and strong hydraulic systems.

Some earth-moving machines used in wide-open strip-mining operations are diesel electric, similar to a locomotive. A diesel engine with thousands of horsepower creates the electricity to power the moving treads, digging booms and ancillary systems. Some of the machines are so large they house several workers for shifts days long.

Under the earth both diesel and electric motors power machines used for boring, digging and removing material. The major factor determining the type of power is the hazards from flammable or explosive gases in the mines.

Mining Equipment Specialization

Mining equipment is specialized to do one task and do it well. A boom shovel lifts and moves material a short distance to a waiting truck or crusher.com' conveyor. A front-end loader moves smaller amounts further distances. Dump trucks move earth, rock and ore from the site to processing or shipping facilities.

In the mines machines with large rotating discs fitted with carbide steel teeth auger away coal. Other equipment quickly transports the coal out of the mine. Drill operators continuously bore into the seam to place explosive charges to expand the mine even farther into the Earth. There is little or no cross-application for this equipment.

Mining Machine Efficiency

Mining by its very nature is a volume business. Miners will move tons of ore to extract a few ounces of gold. Diamonds have even less of a return for the amount of rock mined. Coal is brought out of mines by the ton per minute. Moving this much material means machines must able to hew and lift large loads quickly. Front-end loaders large enough to carry a car and boom shovels able to lift small houses means moving more material with one load. The time saved moving more at once offsets the huge capital expenditure needed to own and operate these machines.

Mining machines are also subjected to very harsh environments and worked continuously around the clock. The engineering and construction quality for this equipment must be the same as for airplanes or laboratory equipment. Down time for repairs is lost revenue and every minute the machine is working is profit. Mining machines must be dependable and easily repaired and maintained in field.
