干涉成像在煤矿巷道定位中的应用研究

Study on application of interference imaging method in mine tunnel location

干涉成像是一种被动源定位方法,经济安全,而且观测系统可以任意排列,灵活性较强。有人员活动及机车作业的巷道是可以激发微弱地震波的被动震源,通过干涉成像对这种地震波进行处理可以定位出巷道的位置。岱庄煤矿实际巷道探测试验表明:干涉成像法对巷道定位有一定的可行性,可以作为巷道探测的一种手段或者辅助手段。

Interference imaging method belongs to a passive source location method, it is economic and safe and its observation system can arranged flexibly. Tunnel with miner activityand tramcar operation was considered as a passive seismic source that can produce weak seismic waves, through processing the data of the seismic waves by using interference imaging method,the roadway can be detected. The field test in Daizhuang Coal Mine showed that there was a certain feasibility in tunnel location by interference imaging method, which could be used as a method or an aiding method to detect mine tunnels.
