摘要
本文针对目前煤矿在巷道掘进过程中超前物探探测结果准确率低、探测参数单一、钻探法施工复杂且成本高的问题,研发了一种随钻钻孔电磁波层析成像超前探水设备,实现了巷道掘进时钻探和物探相结合的随钻超前探测。通过在同忻矿的试验表明,钻孔探测半径在0 m~30 m范围内时可避开井下强干扰背景,可以很好地解决煤矿巷道掘进超前探测问题。
Aiming at the problems of low accuracy of advanced geophysical detection results,single detection parameters,complex construction of drilling method and high cost in the process of coal mine roadway excavation,an advanced water exploration equipment for electromagnetic wave tomography while drilling has been developed,which realizes the organic combination of drilling and geophysical exploration during roadway excavation.The test in Tongxin mine shows that when the drilling detection radius is within 0 m~30 m,it can avoid the strong interference background underground,and can well solve the problem of advanced detection in coal mine roadway excavation.
