摘要
为加强综采工作面机尾处三角区顶板安全,以汾西矿业双柳煤矿33(4)11工作面为背景,通过分析工作面情况及三角区顶板情况,决定采取固安特配合锚杆、锚索进行加强支护,现场实践证明该方法可行,保证了综采工作面机尾三角区顶板稳定,确保了工作面顶板安全。
In order to strengthen the safety of the roof of the triangle area at the tail of the fully-mechanized coal mining face,taking the33（4） 11 working face of Shuangliu coal mine in Fenxi Mining Industry as the background,the anchor bolt and anchor cable are used with to strengthen the support given that the working face and the roof of the triangle area. The practice proves that the method is feasible and the triangle area at the tail of the fully-mechanized coal mining face is guaranteed,which ensures the roof safety of the working face.
