摘要
煤矿井下巷道掘进时,利用直流电法超前探测技术可查明巷道迎头前方断层、裂隙带、陷落柱等地质异常体的位置。本文通过沙巴台某矿探测实例证明此方法对含水断层、小窑、顶板渗水等地质异常体有较好的探测效果,为保证煤矿巷道安全掘进,生产进度起到了关键性的作用。
The coal mine tunnel, advanced detection technology can be found in front of the tunnel in front of faults, fracture zone, karst collapse columns of geologic abnormal body position by dc. This article through the Sabah Taiwan mine detection examples prove that this method has better detection effect on water fault, small kiln, roof water seepage and other geological anomalous body, in order to ensure the safety of coal mine roadway excavation, production scheduling plays a key role.
