Coal is widely distributed over the planet, either as underground seams which must be mined, or as deposits located closer to the earth's surface.How does surface mining work?Surface Mining. 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.How does conventional mining work?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.What is a continuous miner?Continuous Miner. 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.

What equipment is used in mining?Each segment requires the use of specific equipment, but there are several types of mining equipment that are used throughout the industry. This equipment includes excavators, draglines, drills, roof bolters, continuous miners, longwall miners, rock dusters, shuttle cars and scoops.What are continuous miners made of?Continuous miners are machines with massive, rotating arrays of teeth, often made from tungsten carbide. Subterranean coal miners use the machines to scrape coal from coal beds. In particularly dangerous situations, workers control robotic continuous miners remotely.What are the major industries in the mining industry?According to the Bureau of Labor Statistics, the mining industry consists of five major segments: coal mining, gas and oil extracting, metal ore mining, non-metal mineral mining and supporting activities such as resource transportation.Definition of draglinesDraglines. Draglines are enormous earth moving machines that miners use to drag away dirt and expose underlying coal or mineral deposits. Draglines are some of the largest machines on the planet, and can remove several hundred tons of material in a single pass, according to Kentucky Coal Education.What is a miner excavator?Miners traditionally used shovels and steam shovels to break and remove earth, but today’s miners rely on excavators. An excavator is a mobile vehicle that moves on tracks or with standard wheels. It features a rotating platform, off of which comes a hinged arm with a bucket or scoop attached to its end for digging.What is rock duster?Rock Duster.
