Undercut — To cut below or undermine the coal face by chipping away the coal by pick or mining machine. In some localities, the terms "undermine" or "underhole" are used. Underground mine — Also known as a "deep" mine, usually located several hundred feet below the earth's surface, where coal is removed mechanically and transferred to the ...
underground mine electrification, due to the use of a 1,000 m deep hoisting shaft to move ore and waste to the surface. This limited the length of truck haulage routes to distances compatible with the current battery technology in underground mining equipment. In principle, mines stand to save operational costs
A continuous miner machine uses several different electronic systems. In some cases, these durable systems contain software that enables companies to operate mining equipment remotely.

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 seam.
