综采工作面过断层期间延缓了采掘接替，降低了煤炭资源的回收率，干扰了采煤工作面的布置。由于断层区域顶板破碎，工作面过断层期间极易片帮，易发生冒顶事故，影响工作面安全生产，增加了开采成本。本文从降低开采损失，减少工作面搬家次数以及降低开采成本入手探讨了综采工作面过断层技术。
綜採工作麵過斷層期間延緩瞭採掘接替，降低瞭煤炭資源的迴收率，榦擾瞭採煤工作麵的佈置。由于斷層區域頂闆破碎，工作麵過斷層期間極易片幫，易髮生冒頂事故，影響工作麵安全生產，增加瞭開採成本。本文從降低開採損失，減少工作麵搬傢次數以及降低開採成本入手探討瞭綜採工作麵過斷層技術。

During mechanized mining face passing through fault,delays the excavation succeed, reduces the recovery of coal resources, disturbs the arrangement of coalface. Due to fault zone roof broken, working face is eas-ily spalling during passing through fault, the accident of roof caving is easily happened, affects the working face safe production, increases mining cost. Discusses the working face passing through fault technology from reducing mining loss, reducing the number of face moving and mining cost.
