摘要
为最大限度回收煤炭资源,在冲击层附近施工较大断面切眼,面临顶板强度低、淋水等不利因素,通过进一步优化施工工艺,采取多手段联合支护方法,保证了施工安全,取得了较好的效果。
In order to maximize the recovery of coal resources,a large cross-section cut near the impact layer is cut,which is confronted with unfavorable factors such as low roof strength and water spray.By further optimizing the construction technology and adopting multiple means of joint support methods,construction safety,Achieved good results.
