WebHighwall mining is an important surface coal mining method, and it may account for approximately 4% of total U.S. coal production. Highwall stability is the major ground control related safety concern. Ground control plans for highwall mining should specify hole width, web pillar width, barrier pillar width and number of holes between barriers. WebThe highwall mining machine, Terex SHM Miner, is the most advanced, reliable, and efficient highwall mining system in the world. It is the first practical highwall coal mining system capable of mining parallel entries to predetermined depths, thus linking surface and underground operations to maximize coal recovery and profits.
