摘要
详细分析了千秋煤矿冲击地压的形成原因,使用电磁辐射仪、ARAMIS M/E和ESG微震监测系统等多种设备对冲击地压进行预测预报,采用煤层深孔卸压爆破、煤层高压注水、大直径钻孔卸压和预掘疏压硐室卸压的方法对冲击地压进行治理,通过对多种监测数据的研究分析,验证了防治措施的有效性,实现了复合型灾害矿井冲击地压、火灾、瓦斯的综合防治,促进了矿井的安全生产。
In this paper,the formation cause of rock burst in Qianqiu Coal Mine was analysed in detail, many kinds of equipment,inclu- ding electromagnetic radiation meter,ARAMIS M/E and ESG seismic monitoring system and so on,were used to predict rock burst. The pressure-relief and blasting using deep hole,high-pressure water injection,pressure-relief using large diameter boreholes,and advanced dig pressure-relief chamber methods were used to control the rock burst. Through research and analysis of the monitoring data, the effec- tiveness of prevention and control measures was proved, comprehensive control of rock burst, fire and gas was realized, and has promoted the safety production of coal mine.
