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 process and the example of the change of ground pressure activities in Tongkeng mining area of Dachang Guangxi in the past 10 years, and analyzes the characteristics of rock subsidence and the mechanism of ground pressure in metal mines. Through the monitoring and monitoring of underground pressure activities in Tongkeng mining area, it is proved that mine safety production proves that the comprehensive observation, analysis and forecasting of acoustic emission monitoring and ground pressure activities are intensified and targeted prevention measures are taken to ensure the efficient Safe mining.
