摘要
针对浅埋深综采工作面在通过构造带时,工作面易发生大面积漏顶事故的问题,根据沙坪煤矿1805工作面实际情况,对漏顶原因进行了分析,并对发生漏顶后的处理方案进行了总结,提出了超前预防漏顶技术措施,现场实际应用效果良好,对浅埋深综采工作面快速通过构造带具有一定借鉴意义。
In view of the problem of large area roof leakage accident in shallow buried deep fully mechanized working face when passing through the structural belt,according to the actual situation of 1805 working face in Shaping Coal Mine,the causes of roof leakage are analyzed,and the treatment scheme after roof leakage is summarized,and the technical measures for advanced prevention of roof leakage are put forward.The field application effect is good,which has certain reference significance for the rapid passage of shallow buried deep fully mechanized working face through the structural belt.
