Longwall mining - Global Energy Monitor

2021-9-10  Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 1-2 m thick). The longwall "panel" (the block of coal that is being mined) is typically 3-4 km long and 250-400 m wide. Longwall mining produced 176 million tons of coal in 2007, about 15 percent of total U.S. production.

2020-2-14  Conditions in a longwall mine play havoc with traditional staple-lock and super-staple-lock couplings. Operating pressures of 5,000 psi in the hydraulic hoses connecting the shields on your longwall miner put 60,000 ft-lbs of force against the fittings. That’s a lot for a staple to withstand. Moreover, hoses and
