针对贵州宏达煤矿第一开采水平上部采区煤层埋藏浅、顶板破碎且不完整、矿山压力大、且易受地表水影响等问题,对过去开切眼支护方式及破坏机理进行分析。采用新的施工方案。改进后的施工设计方案有效地控制了在施工和综采设备安装期间开切眼围岩的变形破坏,在一定程度上有效地保证了矿井的安全生产。 In view of the problems such as the shallow coal seam in the upper mining area in the first mining level of Hongda Coal Mine in Guizhou Province, the roof is broken and incomplete, the pressure in the mine is high and the surface water is easily affected, the open cut support methods and failure mechanism in the past are analyzed. Adopt new construction plan. The improved construction design effectively controlled the deformation and failure of surrounding rock during the construction and fully mechanized mining equipment installation, which effectively ensured the mine’s safe production to a certain extent.
