摘要
煤矿井下超前探测巷道掘进工作面前方的富水异常体是预防水害事故、保证巷道安全掘进的一个技术难题。利用瞬变电磁技术的超前探测装置,解决超前预报掘进工作面水害的难题,经实践检验效果良好。
To detect the water - bearing area in front of the driving face of a drift in coal mine is very important for tunnel＇ s salty driving and preventing the occurrence of water disasters. Underground whole space transient electromagnetic method was used to detect water-beating zones ahead of tunneling. The results proved that the method is useful and effective.
