摘要
矿井水害一直严重威胁煤矿安全生产,为保证巷道安全掘进,必须查明巷道前方的富水性特征。利用矿井瞬变电磁发对低电阻率体有反应敏感、分辨率高的优点,对晋牛煤矿巷道进行超前探测。通过与实际揭露情况对比,有效证明了矿井瞬变电磁法能够查明富水区域的分布情况,为煤矿安全掘进提供技术保障。
Mine water has been a serious threat to the safety of coal production. In order to ensure the safety of tunnel driving, the characteristics of rich water front must be identified in front of tunnel driving. Based on this, this paper uses the advantages of sensitive and high resolution of TEM to low resistivity body to do advanced detection in roadway in Jinniu Coal Mine. Compared with the actual situation revealed, it can be indicated that mine TEM can effectively identify the distribution of water-rich area in front of the laneway, providing the technical support for mine tunnel driving safely.
