Coal Mining
Underground Mining Room and Pillar mining, the most common type of underground coal mining, coal seams are mined by a "continuous miner" that cuts a network of "rooms" into the seam. As the rooms are cut, the continuous miner simultaneously loads the coal onto a shuttle or ram car where it will eventually be placed on a conveyor belt that will move it to the surface.

Coal mine reclamation
· Coal mine reclamation is the rehabilitation of land after coal mining operations have stopped. It is a requirement of the Surface Mining Control and Reclamation Act (SMCRA) of 1977.. As mining operations cease bulldozers and scrapers are used to reshape the disturbed area. Reclamation should allow for the area to be resistant to soil erosion and, based on the soil requirements, fertilized .

What is Surface Mining? (with pictures)
Quarry mining is one type of surface mining. Strip mining is a form of surface mining that is primarily used for coal excavation. The rock and dirt covering the ore is removed one strip at a time. Once the ore has been taken from the first strip, a second strip is cut next to it, and the waste from the second strip is used to back fill the first.

Open Pit Mining
The surface mining methods are: (i) open pit mining, (ii) drift mining, (iii) slope mining, (iv) contour mining, and (v) auger mining. The characteristic that distinguishes open pit mining is the thickness of the coal seam insofar as it is virtually impossible to backfill the immediate mined out area with the original overburden when extremely thick seams of coal are involved.
