All machines, drills, and vehicles in a coal mine operate on either fuel or energy. When operations and processes are well scheduled, planned, tried, and tested, fuel and energy are used in a highly practical and an efficient manner. There is no wastage of fuel and energy on processes that are later deemed useless or redundant.

Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice, typically 0.6–1.0 meters thick. The longwall panel (the block of coal that is being mined) is typically 3–4 km long and 250–400 meters wide. ... The mining process involves the use of a large cutting machine, the longwall shearer ...
Shortwall mining currently accounts for less than 1 percent of deep coal production, involves the use of a continuous mining machine with movable roof supports, similar to longwall. The continuous miner shears coal panels 150-200 ft wide and more than a half-mile long, having regard to factors such as geological strata.
Large stripping machines with excavating wheels used in surface coal mining are employed in other types of open-pit mines. Water inflow was a very important problem in underground mining until James Watt invented the steam engine in the 18th century. After that, steam-driven pumps could be used to remove water from the deep …
