淮南大通煤矿已闭坑多年,采煤塌陷区基本稳定,由于闭坑后小煤窑滥挖乱采留下了大量不明的采空区,给当地矿山环境治理和生态恢复带来了一定的危险性。针对上述问题,采用Terratem瞬变电磁仪对大通煤矿原4#井采空区及其受小煤窑重复采动活化情况进行了现场探测。
Datong Coal Mine in Huainan has been closed for many years and the coal mining subsidence area is basically stable. Due to indiscriminate digging and mining of small coal mines after the closure of the pit, a large number of unknown goafs have been left, posing a certain danger to the local mine environmental governance and ecological restoration . In response to the above problems, the Terratem transient electromagnetic instrument was used to detect the goaf of the original No.4 well of Datong Mine and its repeated mining and activation by small coal mines.
