摘要
5306工作面揭露F5断层时顶板及煤壁出现破碎现象,工作面顶板维护难度大,片帮严重,移架困难。对断层处顶板采取深孔预裂,提出了铺设聚氨酯纤维网配套JW型锚索梁以及超前支护措施,提高了断层处顶板的稳定性,取得了较好效果。
When the F5 fault is exposed in 5306 working face,the roof and coal wall are broken.It is difficult to maintain the roof of the working face,the spalling is serious and the frame moving is difficult.Deep hole pre cracking is adopted for the roof of the fault,and the laying of polyurethane fiber mesh supporting JW type anchor cable beam and advanced support measures are put forward,which improves the stability of the roof at the fault and achieves good results.
