基于微震监测技术的深部岩爆预警和断层突水监测

三山岛金矿直属矿区进入深部开采时出现岩爆现象，同时生产区域存在由于岩爆诱发的矿柱失稳和顶板冒落的危险，需要进行监测和预警。基于适合监测深部金矿安全开采的微震监测系统检测结果，研究基于微震监测的深部岩爆预警技术思路，分别研究了岩爆危险区域的预报、微震监测划分采场安全等级、断层突水的微震监测等内容。通过研究达到全面监控目标区域的岩石稳定状况和动态，实现了深部开采的监测和预警。

Deep Rockburst Warning and Fault Water-Gushing Monitoring Based on Seismic Monitoring Technology

The phenomenon of rock burst appears while deep mining in Sanshandao Gold Mine. The dangers of instability and roof collapse are induced by rock burst in production area, which requires monitoring and early warning. Based on the test results of micro seismic monitoring system for monitoring the safety of deep gold mining, the technical approaches of pre-warning for deep rock burst at deep zone are studied based on the seismic monitoring, including the forecast of dangerous rock burst zone, security level of the stope based on the micro seismic monitoring, micro seismic monitoring of water inrush etc. The monitoring and early warning of deep mining are achieved through the comprehensive monitoring of the rock steady state and dynamics of the target area.
