摘　　要：鹤煤公司各矿井已相继进入深部开采,深部高应力条件下水泵房硐室群维护愈发困难。通过对矿井深部高应力条件下水泵房硐室群变形破坏原因的分析,确定高地应力、工程应力集中、施工顺序不合理、支护方式不合理是深部水泵房硐室群变形破坏的主要原因,提出了优化原设计中水泵房布置方式,增高支护强度,减少巷道间工程应力相互干扰,降低水泵房硐室应力集中程度,加强围岩整体性等有针对性、系统的解决方案,实现水泵房硐室稳定性整体提高、维护难度降低,同时减少水泵房施工工程量;在六矿-600m水平水泵房完成了现场试验,实现了提高硐室群稳定性的设计目标。Coal mines of Hemei Corporation had started deep mining , high stress condition in deep mine made pump room caverns supporting more and more difficult .By analyzing deformation and failure of pump room caverns , it was believed that high geo-stress, mining stress concentration , unreasonable construction sequence and supporting manner were main causes .The solution was put forward that applying optimizing pump room location , improving supporting strength , reducing mutual disturbance of engineering stress be-tween roadways , reducing stress concentration degree and reinforcing surrounding rock integrality , which improved cavern ’ s whole stability, redued supporting difficulty and construction quantities .Site test at -600m pump room of 6th Mine showed that this technolo-gy realized the design goal of improving cavern stability .
