| 摘 要： | 通过矿区勘探的三个典型实例,介绍了使用CUGTEM-2002型瞬变电磁系统在探测小窑采空区积水和陷落柱方面的应用。根据瞬变电磁法对低阻地质体的灵敏性,采用在已知地质异常位置布设测线获取地质异常资料特征,然后推断整个测区资料成果的勘探方法,可取得较好的地质效果。实践证明,瞬变电磁法是探测金属矿体、小窑采空区等地质异常体的一种有效手段。

| Abstract: | Through three typical case studies of mining area prospecting,the author introduced the application of CUGTEM-2002 type transient electromagnetic system used in gob area water and subsided column prospecting.According to the method's susceptibility toward low resistivity geologic body,to use known geologic anomaly location spread lines and acquired geologic anomaly data characteristics,then deduct data in the whole area,thus better geologic results may be obtained.Practices demonstrate that the method is an effective means to detect geologic anomaly bodies of metal ore body and small mine gob area. |
