突出煤层巷道掘进隐伏构造微震超前探测技术应用研究
Research and application on the advanced detection technology for buried fault based on microseism system in outburst tunnel
【摘要】 介绍在突出煤层巷道掘进过程中,通过布置传感器实时采集微地震信号,利用微震监测技术超前探明了掘进巷道采动影响区顶底板的隐伏断层(构造)空间状态及其影响范围,从而实现对地质异常区域进行及时微震预警,通过采取科学合理的针对性安全技术措施,保证突出煤层巷道掘进施工安全。
【Abstract】 In this paper,based on the microseismic monitoring technology,the space state and its sphere of influence for buried fault of mining-affected zone at roof and floor in the process of excavating of outburst tunnel was detected in advance by means of real-time microseismic signal acquisition,based on the above,the regional geological anomalies can be warned timely,furthermore,by taking a scientific and rational targeted safety technical measures,the construction safety of outburst tunnel was ensured.
