Longwall Miner. 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.

Coal has a bad name: Accidents in coal mines; mountaintop removal mining; acid rain; and, especially, global warming. Burning coal produces more greenhouse gases than other fossil fuels for the same amount of energy. But coal's supporters are quick to point out that there is no ready alternative. Coal provides nearly half of America's electricity.

Coal mines operated without electricity. Electricity began to be adopted in mining and manufacturing in the late 1880s and the 1890s. (Electricity was first introduced into Ohio's bituminous coal mines in 1889.) The introduction of electricity in coal mines greatly facilitated the introduction of laborsaving machinery. 1891.

Wastetoenergy plants burn municipal solid waste (MSW), often called garbage or trash, to produce steam in a boiler, and the steam is used to power an electric generator turbine. MSW is a mixture of energyrich materials such as paper, plastics, yard waste, and products made from wood. For every 100 pounds of MSW in the United States, about 85 ...

The coal produces heat when we burn it, and that heat is used to boil water, making steam. The steam rises, and is used to spin turbines, which are connected to generators. It is the generator that makes the electricity by spinning a magnet, which causes electrons to move around in a tightly coiled wire. Electrons can be either positive or ...
