长榆河煤矿15103综采工作面锚杆锚索顶板支护分析

Bolt and Anchor Cable Roof Support in 15103 Fully Mechanized Mining Face of Changyuhe Coal Mine

确保综采工作面安全高效开采是煤矿生产的核心,而顶板控制又是综采工作面安全高效开采的关键。针对长榆河煤矿15103综采工作面开采15号煤层时,顶板完整性差、工作面易发生大面积冒顶事故的问题,采用了锚杆锚索支护的技术措施管理顶板。现场实践结果表明,利用锚杆锚索支护来进行工作面的顶板管理,能确保工作面正常回采,而且具有显著的技术经济效果。

Ensuring the safe and efficient mining of fully mechanized mining face is the core of coal mine production,and roof control is the key to the safe and efficient mining of fully mechanized mining face.In view of the problems of poor roof integrity and large-area roof fall accident in 15103 fully mechanized mining face of Changyuhe Coal Mine,the technical measures of bolt and anchor cable support were adopted to manage the roof.The field practice results showed that the roof management of the working face with bolt and anchor cable support could ensure the normal mining of the working face,and had remarkable technical and economic effects.
