There are two types of room and pillar mining–conventional mining and continuous mining. Conventional mining is the oldest method and accounts for only about 12% of underground coal output. In conventional mining, the coal seam is cut, drilled, blasted and then loaded into cars.
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 landscapes.

The effects of mining coal on the environment. There are 2 ways to mine coal – Strip Mining and Underground Mining – both ways have their own impact to the environment and health. We know it but coal is such a cheap energy source that we don't want to let go of it. The negative effects of coal mining cannot be disputed:

Coal mining deep underground involves a higher safety risk than coal mined in opencast pits, due primarily to problems associated with mine ventilation ...
Two ways of accessing coal. Surface mining. methods used when ore deposits are located to the earth' surface. Underground mining. Shaft (elevator), slope (conveyor belt), and drift. Mountaintop removal. Cheaper access, more than one coal seam, land reuse. Removing the top of a mountain with explosives to access a reserve.

Mining. Mining is the process of extracting coal, oil, and natural gas from the ground. Strip mining (also known as open cast, mountaintop, or surface mining) involves scraping away earth and rocks to get to coal buried near the surface (Greenpeace, 2010). This often has significant impact on the surrounding land, plants, and animals.

Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the ground's surface, and about two-thirds of coal production comes from surface mines.
There are two main methods of underground mining: room-and-pillar and longwall mining. Room-and-pillar mining. In room-and-pillar mining, coal deposits are mined by cutting a network of 'rooms' into the coal seam and leaving behind 'pillars' of coal to support the roof of the mine.
Coal can be extracted in two ways: surface mining and deep mining. Surface mining, which includes the technique of open-cast mining, retrieves coal from shallower seams. However coal seams can be thousands of feet underground.
