摘　　要：随着矿山开采逐渐往深部延伸,出现了轻微岩爆现象,生产区域内存在由岩爆诱发的矿柱失稳和顶板冒落的危险。根据三山岛金矿深部矿体地质条件和围岩实际地质情况,研制了新一代的BMS微震监测系统,构建了矿山预警系统。该系统能有效监测到采场矿柱失稳和顶板冒落的微弱振动信号,分析微震波形,监测岩爆的发生,为深部矿体安全开采提供依据。With the gradual extension of mining operations into deeper levels,minor rockburst phenomena have emerged,posing risks of instability in mining pillars and roof caving induced by rockbursts within the production area.Based on the actual geological conditions of deep ore bodies and surrounding rocks in Sanshandao Gold Mine,a new generation of microseismic monitoring system has been developed,in order to establish a mine early warning system.This system can effectively monitor faint seismic signals associated with the instability of mining pillars and roof caving in the mining area,analyze microseismic waveforms,and detect occurrences of rockburst events,providing basis for the safe mining of deep rock mass.
