Mining into such abandoned voids poses a great safety risk to personnel, equipment, and production from inundation or toxic/explosive gas release. Often, surface or underground drilling is employed to detect the mine void and evaluate the hazards, sometimes with disastrous results.

Highwall Miners Information | Engineering360

The highwall mining machine is positioned on the pit floor or on a bench beside the highwall in front of the coal seam. A cutterhead attached to a string of push beams is thrust into the seam. The coal is mined by the shearing action of the cutterhead that is raised and lowered to dig out the entire height of the coal seam.

Coal mining Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the
