摘　　要：系统地介绍了广西大厂铜坑矿区近10年以来地压活动发生变化过程与实例,综合分析了金属矿山岩层塌陷发生特征、地压活动发生机理。通过铜坑矿区地压活动监测监控、确保矿山安全生产的实例证明,加强声发射监测和地压活动综合观测分析与预报预警,有针对性地采取防患措施,是可以确保复杂难采矿体高效安全开采的。This paper systematically introduces the change process and examples of ground pressure activities in Tongkeng Mine since the past 10 years,and comprehensively analyzes the characteristics of strata collapse and the mechanism of ground pressure activity in metal mine. The ground pressure monitoring has ensured the safety of production in Tongkeng Mine, this indicates that the highly efficient and safe mining of complex hard-to-mine orebody can be ensured by strengthening the acoustic emission monitoring, comprehensive observation and analysis as well as forecast and early warning of ground pressure activity, and taking corresponding preventive measures.
