outside the mining area for placement and storage In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ()In some situations in the eastern United States, a coal seam occurring near the top of mountains is.
The preferred choice in underground coal mining is the Longwall technique which accounts for roughly 301 percent of all underground coal production This process involves a cutting head that moves back and forth across a panel of coal Once cut, the coal falls onto a flexible conveyor for removal.
Coal mining takes place in two ways: surface mining and underground mining Both pose threats to the environment, but in different ways Surface mining takes place primarily on mountaintops Setting up mining operations requires clear-cutting, often of vast tracts of forests and vegetation This removal disturbs habitats and alters landscap.

In the extraction process, numerous pillars of coal are left untouched in certain parts of the mine in order to support the overlying strata The mined-out area is allowed to collapse, generally causing some surface subsidence Extraction by longwall mining is an almost continuous operation involving the use of.
After mining, coal is crushed and washed to remove the surrounding soil and rock Coal sludge, also known as slurry, is the liquid coal waste produced by mining activiti The washing process generates huge amounts of liquid waste Another form of liquid coal waste is acidic mine runoff, as sulfuric acid forms when coal is exposed to air and.
The environmental toll of underground mining is significant It includes air pollution, changes in water-flow patterns, chemical and gas seepage into water supplies and soil, inaccessible fires in abandoned mines, and dramatic changes in land composition that can make the area unusable after the mining operation is done [source: Saxena] Then there is the human toll.
For coal deposits, like most other minerals, drilling is a key to identifying in detail the grade and size of the resource, both prior to mine development, and during operations Mining operations employ a variety of drilling methods based on the requirements of the project In the majority of cases.
