Strip mining, Open pit mining and Mountaintop removal mining
because they cause pollution by taking the dirt and rocks to neighboring valleys
Here are two of the main categories of mining:Underground Mining - Underground modes of access include drift, slope, and shaft mining, and actual mining methods include longwall and room and pillar mining. Drift mines enter horizontally into the side of a hill and mine the coal within the hill. Slope mines usually begin in a valley bottom, and a tunnel slopes down to the coal to be mined. Shaft mines are the deepest mines; a vertical shaft with an elevator is made from the surface down to the coal.Surface Mining - Surface-mining methods include area, contour, mountaintop removal, and auger mining. Area mines are surface mines that remove shallow coal over a broad area where the land is fairly flat. Huge dragline shovels commonly remove rocks overlying the coal (called overburden).
The process is called mining or extraction.
organic materials - if it means minerals then process is called mining.

Coal mining is a cause for mountaintop removal. It is generally considered to be a pollution problem when the waste material from the process is allowed to wash into streams and may be considered a blight on the landscape.

Coal is primarily dug from underground mines. These mines are typically located in coal-rich regions and are accessed by tunnels and shafts. Surface mining methods, such as strip mining or mountaintop removal, may also be used in areas where the coal seam is close to the surface.
