摘要
针对矿井超前地震技术存在的多震源少测道观测系统、震源单一以及波形分离问题,以矿井巷道超前探测技术为基础,提出一种一次激发、多点多道接收的新型分布式巷道超前探测系统。该系统应用于寺河矿西三盘区,试验探测结果与实际揭露情况相符,准确率达到85.2%,误报率为14.8%,漏报为0。
Aiming at the problems of multi-source and low-trace observation system, single source and waveform separation existing in mine advanced seismic technology, a new distributed roadway advanced detection system with one excitation and multi-point and multi-channel reception is proposed on the basis of the advanced detection technology. The system is applied to the west three panel of Sihe Coal Mine. The experimental results are consistent with the fact. The accuracy rate is 85.2%, the false alarm rate is 14.8%, and the omissive alarm rate is 0.
