摘要
本文以鲍店煤矿1310综放工作面为研究对象,采用钻孔基点位移、钻探等综合方法,对中硬覆岩厚煤层综放开采冒落带特征进行了探测,获得了综放开采条件下冒落带发育特征,研究成果对于提高资源回收率及矿井安全生产具有重要意义。
In this paper,taking fully mechanized sublevel caving face of No.1303 in Baodian coal mine,based on the methods of drilling,hole basic point displacement and other comprehensive methods,caving zone characteristics of thick coal seam of medium hard rock in fully mechanized sublevel caving mining is detected,and its characteristics is obtained,the achievements have important significance for the improvement of resources recovery and safety production.
