More than two-thirds of coal extracted underground is done by a continuous miner, a tractor with a mounted cylindrical grinder that breaks coal away from the seam. The continuous miner deliberately leaves undisturbed pillars of rock and coal in the mining area to create natural supports for the ceiling. This is known as room and pillar mining. When most of the coal seam has been extracted, the pillars then are mined one by one, allowing the roof to naturally cave in.
Twenty percent to 30 percent of mined coal underground is from longwall mining. This is performed by a mechanical cutter that shears coal off from a panel on the seam. The panel being worked on may be up to 800 feet in width and 7,000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area. Hydraulically powered shields over the machine provide ceiling support. Longwall mining is more efficient than room and pillar mining, but the equipment is more expensive.
For extracting coal which lies close the surface, huge drag-line shovel machines remove the topmost layers of soil and rock, exposing the coal, which is then removed by smaller machines. Surface mining may involve removing sections of hills or top layers of a flat surface area. The layers of rock and dirt covering the coal are reserved for until the coal is removed, at which point the the dirt and rock is replaced, the mine covered over, and the environment restored as much as possible to its original condition.
Conventional mining employs crews of miners who use explosives and drills to extract coal, which is then loaded onto cars for transport to the surface. This method presents higher risks to miners because of the explosives. The coal dust generated by the drilling and explosives is also a health hazard when continuously inhaled. This is the oldest method of coal mining.
The machine may thus become any one of the following- a crane, a clam shell, a dipper shovel, a drag line, a pull shovel or a back-hoe. Equipment 5. Dipper Shovel This is a machine employed for excavating soft rock or loading fragmented rock from a bench and is very commonly used in mines. It is usually mounted on crawler chains.
These pages show mining machines, and offer some information about the introduction of machinery into mining.
The point of the pages is to appreciate the dynamic quality of the industrial revolution. Other pages reviewed the work of a coal miner and coal mining in the 1870s. These pages will be about the coal industry at the turn of the twentieth century. These pages will show the introduction of laborsaving machinery into coal mining. For the course quotHistory 563quot the machinery has no intrinsic interest as artifact. However, the human story of the introduction of machinery is important, as is, of course, the business and technological dynamics behind its introduction.
In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted. The land can then be used for croplands, wildlife habitats, recreation, or offices or stores. Underground mining ...
From the iconic minecart of the American Gold Rush to the unfathomably big Bagger 288, and the classic CAT 797 to todays cutting edge unmanned and electric vehicles, we trace the evolution of mining machines through time.
Mine Machines, Coal Cutting In the early days of using coal, loose coal would be gathered by hand where coal seams reach the Earths surface outcrop. Hand tools such as picks were used to get the coal. As seams were mined underground, sharpened hand tools were the standard equipment and continued to be used in small mines until the 1950s.
a machine for producing a cut in a seam of a mineral usually coal in underground operations. The cut facilitates the breaking of the remaining part of the layer by means of mechanical devices or explosives. Coal-cutting machines can operate in gently sloping, sloped, and steep seams.
The use of pneumatic coal-cutting machines in Russia dates to the 1870rsquos they were percussion machines imported from Great Britain on the Grushevskii anthracite and Nikitovskii coal mines of the Donbas. In 1913, 1.7 percent of the coal in the Donbas was mined with coal-cutting machines.
The KMP-1 and KMP-3 coal-cutting machines are equipped with friction fluctuating speed regulators, which provide stepless regulation of the speed of operation of the feed from 0 to 0.86 mmin the KMP-1 and from 0.3 to 1.4 mmin the KMP-3. The cutting-loading machines based on these cutters are used in combination with explosive breaking of coal.
The all-around mechanization of extractive work in the mines of the USSR with the use of mining combines and complexes has limited the use of coal-cutting machines to extracting hard and tough coals such as the Kizel region in the Urals, for the extraction of which reliable coal combines have not yet been created.
Trams are used to transport miners, minerals and waste. Lifts carry miners into and out of mines, as well as moving rock and ore out, and machinery in and out of underground mines. Huge trucks, shovels and cranes are employed in surface mining to move large quantities of overburden and ore.
According to the World Coal Association, the primary uses of coal are in electricity generation, the creation of liquid fuel, the production of steel and cement manufacturing. There are two primary types of coal, thermal coal and metallurgical coal. Thermal coal goes into fuel and electricity applications, while metallurgical coal is better suited to manufacturing and chemical applications.Read more
The primary use of coal is as a source of energy. Nations around the world use coal to produce electricity. Steel manufacturers also use coal to create a fuel called coke. Coal is formed from plants that were buried in the earth millions of years ago.Read more
In underground mining the mining machine if mining is continuous can be used as a sound source, and receivers can be placed in arrays just behind the working face. For drilling and blasting operations, either on the surface or underground, blast pulses can be used to
Apr 03, 2017nbsp018332Coal Mining is the term that encompasses the physical extraction or removal of coal from the Earths Surface. When coal is used as fuel in power generation, it is referred to as Steaming or Thermal coal while those which are used to create coke for steel manufacturing is referred to as Coking or Metallurgical Coal. Coal can be mined by both ...
Coal mining - Coal mining - Underground mining In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities ...
