| 摘 要： | 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。

| Abstract: | Huainan Datong coal mine has been closed for many years, the coal mining subsidence was basically stable. But after the closure, many small coal mines still mining resources indiscriminately,which has left a large amount of unknown goaf. It is a threaten to the local mining environmental management and ecological restoration. In allusion to the problems mentioned, transient electromagnetic(TEM) instrument was used in the study area to detect the he forth well of Datong coal mine goaf. |
