| 摘 要： | 探讨了用矿井瞬变电磁法探测采煤工作面内部和掘进巷道前方的水文钻孔的位置,对其富水性进行了定性评价,总结出水文钻孔在视电阻率断面图上的响应特征,即在顺煤层方向呈圆形异常反映,而在煤层顶、底板方向呈狭长椭圆形特征.该方法在探测隐伏含水陷落柱构造方面也有较好的应用前景.

| Abstract: | This paper discusses the utilization of the mine transient electromagnetic method to detect the location of hydrological borehole that lies in the coal layer or in front of the laneway, and gives a qualitative appraisal of its hydrous characteristics. The response characteristics of the hydrological borehole reflected in the apparent resistivity pseudo-section are summarized. It is detected that the anomaly assumes circular response in the same direction as the coal layer and shows narrow elliptic response in the direction of the top and bottom of the coal layer. This method also has wide prospects in detecting the structure of the collapsed column. |
