基于某矿1306工作面运输巷冲击地压事故,结合SOS微震监测系统矿震能量统计结果,分析研究了静载荷和动静载叠加作用下巷道围岩破坏规律。结果表明:随着震源的远离巷道,底板所受扰动影响急剧衰减,而两帮所受扰动影响成比例下降。研究成果为受矿震扰动巷道围岩控制提供了一定的指导。
Based on the statistical analysis of mine seismic energy of SOS microseismic monitoring system, the failure law of surrounding rock of roadway under the action of static load and dynamic load is analyzed. The results show that with the source far away from the roadway, the influence of the disturbance on the floor plate drastically declines, while the influence of disturbance on the two sides decreases proportionally. The research results provide some guidance for the surrounding rock control by mining-induced disturbance roadway.
