物探与钻探结合在巷道掘进超前探测中的应用

Application of Geophysical Exploration Combined with Drilling in Advance Detection of Roadway Excavation

以山西某矿60901工作面回风顺槽掘进为工程背景,采用直流电法探测、瞬变电磁法等物探手段,并结合钻探进行验证,勘探结果表明,在掘进工作面前方60-80m范围内存在有落差在4-5m的正断层,断层有一定的导水性,在掘进过程中需要做好排水以及强化巷道支护工作,确保巷道掘进安全进行。

Taking the 60901 working face of a mine in Shanxi as the engineering background,using geophysical methods such as direct current method detection and transient electromagnetic method,combined with drilling,the exploration results show that there is a range of 60~80m in front of the heading face.There is a normal fault with a drop of 4~5m.The fault has a certain water conductivity.In the process of excavation,it is necessary to do drainage and strengthen the roadway support work to ensure safe roadway driving.
