摘　　要：以岳城煤矿3号煤三盘区下分层综采工作面设计为例,采用巷道外错布置形式,将两个小工作面合并成一个综采工作面,最大限度地回收边角煤柱,缓解了矿井衔接紧张的局面,实现了科学、安全、高效的资源回收.Taking Yuecheng Coal Mine as an example,two small working faces are combined into one comprehensive working face by adopting the form of staggered layout outside the roadway,so as to recover the corner coal pillars to the maximum extent,alleviate the tense situation of mine connection,and realize the scientific,safe and efficient resource recovery.

关 键 词：下分层 综采工作面 设计优化 空巷
