【摘要】 根据矿井地质条件,通过实践和三维勘探资料,分析了许疃煤矿7219大采高工作面的断层情况,以过落差5 m逆断层及3 m正断层为例,介绍综采工作面过断层技术方法,并提出了强化顶板、煤壁管理,加强设备维修管理、加快推进度等安全管理办法,为其他矿井类似工作面过大断层提供借鉴。更多还原

【Abstract】 According to the geological conditions of 7219 working face,based on three-dimensional survey data and field practice,this paper introduced fault conditions of the 7219 large mining height fully-mechanized working face in Xutuan Coal Mine.Taking working face passing through 5 m high reverse fault and 3 m high normal fault as an example,the paper introduced the technology of working face passing through faults.It also proposed some safety management methods,such as strengthening management of roof and coal wall,paying attention to equipment maintenance,speeding up the progress and so on.All this have reference to other coal mines.更多还原
