瞬变电磁法探测煤矿采空区的应用分析

Application Analysis on Transient Electromagnetic Method in Detecting Gob in Coal Mine

煤矿采空区是引起地质灾害的主要因素之一,对其进行高效、准确的勘查非常重要。瞬变电磁法具有分辨率高、与探测地质体耦合性好、对低阻地质体反应灵敏,而且施工方便、快捷、成本低、效率高等特点,是探测煤矿采空区位置的最佳方法之一。通过实例,对瞬变电磁法在探测煤矿采空区中应用及良好效果进行了分析。

Coal mine gob is one of the main factors that cause the geological disasters,it is very important to make an efficient and accu- rate exploration. Transient electromagnetic method has a high resolution and has good coupling features to the geological object, and it has sensitive reaction to low resistivity geological object, in addition, it＇s fast and easy to construct, and the cost is low, the efficient is high. It＇s convenient construction ,fast ,low cost ,high efficiency, is the best way to explore the gob in coal mine. Based on the example analysis, the application and good results of transient electromagnetic method were analysed in the detection of coal mine gob.
