摘　　要：10306工作面为磁窑沟煤矿10-2号煤层不规则边角煤圈定的最后一个长壁综采面,该工作面内包含多条原采面遗留的回撤通道、胶辅顺槽、回风绕道、盘区回风大巷等空巷道。针对10306工作面内空巷多、巷道应力集中、冲击地压危险程度高的实际情况,从工作面设计、生产系统优化、空巷顶板管理等方面研究该工作面合理的布置方案,并制定相应安全技术措施,保证方案顺利实施。实践证明,磁窑沟煤矿10306工作面采掘过程巷道顶板支护有效,能够满足矿井安全生产要求。The working face of 10306 was the last long-wall fully mechanized mining face of No.10-2 coal seam of irregular corner in Ciyaogou Mine.There were withdrawal roadways,auxiliary transport roadway,return detour,return roadway in this face.Aiming at the problem of abandoned roadways,stress concentration,rock burst,the reasonable layout scheme of the working face was studied from aspects of working face design,production system improvement and roof management of empty roadway,and corresponding safety technical measures were formulated to ensure the smooth implementation of the scheme.The practice proved that the roof support of the 10306 working face in Ciyaogou Mine was effective and met the requirements of mine safety production.
