Study on Fracture Behavior of Directly Covered Thick Hard Roof Based on Bearing Capacity of Supports

Mine pressure at the working face is severe due to it being directly covered by a thick hard roof. To further investigate the technology of controlling the mine pressure of a thick hard roof, the upper working face of 13,121 in Gubei mine of Huainan mining area was used as the engineering background...
