Room-and-pillar mines allow for continuous mining. This process uses robotic equipment to move vast amounts of coal quickly. Longwall mining mines a single coal seam in one single tunnel, rather than the many rooms used in the room-and-pillar technique. Contour mining is similar to longwall mining, but it follows the contour of a …
The coal mining wastes and coal processing by-products can pollute water in several ways, directly and indirectly.

Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
Coal processing, mainly for reducing ash and sulfur contents in the mined raw coal, requires a subset of processing technologies. Some problems in coal processing arise from the way the sulfur and ash are bonded and the need to keep the water content in the cleaned coal low.
