摘　　要：黑岱沟煤矿6号煤层采用分层综放开采工艺,资源回采率较低,文章通过对602工作面的资源损失构成分析,得到该矿综放开采主要资源损失发生在区段煤柱损失、两端头不放顶损失和放煤工艺损失等,并从推广无煤柱开采、提高工作面长度、降低初末采资源损失和减少采空区浮煤等方面对综放开采回采率提高技术进行了分析研究。A slicing fully mechanized top coal mining technology was applied to No. 6 seam in Heidaigou Mine and the mining rate of the coal resources was low. With an analysis on the resources lost composition of No. 602 coal mining face, the main resources lost occurred of the fully mechanized top coal caving mining were the sectional coal pillars lost, no top coal caving of the two face ends and top coal caving technology. An analysis study was conducted on the technology to improve the mining rate of the fully mechanized top coal caving mining from the promotion of the pillarless mining, the increasing of the mining face length, the reduction of the initial and terminal mining resources lost and the ground coal in the goaf.
