Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step by-step mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.

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. ... In conventional mining, explosives and cutting tools are used. In continuous mining, a sophisticated machine ...

Highwall Miner. ( 1) ( 2) The machine is generally operated from a bench that is created by the removal of overburden material and coal by way of contour surface mining around the perimeter of a coal seam. Other highwall applications include previously augered areas and trench mining. In a contour surface application, a minimum bench width of ...

The coal mining industry has also begun to invest in IMD machines, permanent magnet motors, and other major equipment including emulsion pumps, belt tailpieces, and AFCs. The explosion-proof and intrinsically safe IMD machine for mining is an innovative solution combining a motor with a drive and control technology for high …

Therefore, this manuscript proposes a new identification method of surface cracks from UAV images based on machine learning in coal mining areas.
