红柳煤矿2#煤层顶板破碎、隔水层薄,导致锚索孔导水、巷道围岩变形严重,给巷道顶板支护造成了很大困难,同时锚索孔导水削弱了支护强度.为解决此类问题,该巷道顶板全部采用短锚索支护,有效地解决了巷道顶板锚索孔导水问题.同时对破碎顶板围岩变形起到了有效抑制作用,减小了顶板的下沉,确保了巷道的安全.
紅柳煤礦2#煤層頂闆破碎、隔水層薄,導緻錨索孔導水、巷道圍巖變形嚴重,給巷道頂闆支護造成瞭很大睏難,同時錨索孔導水削弱瞭支護彊度.為解決此類問題,該巷道頂闆全部採用短錨索支護,有效地解決瞭巷道頂闆錨索孔導水問題.同時對破碎頂闆圍巖變形起到瞭有效抑製作用,減小瞭頂闆的下沉,確保瞭巷道的安全.

The second layer of Hongliu coal mine roof is broken,water-resisting layer is thin,which leads to anchorage cable hole water-flowing,serious roadway surrounding rock deformation,causes great difficulty for roadway roof supporting and reduces the anchor supporting.The roadway roof uses anchor supporting to solve the problem of anchor water diversion,prevent broken roof surrounding rock deformation,reduce the roof sinking and ensure the roadway safety.
