摘　　要：从电法超前探测技术的应用原理、实施方法等方面分析,分别阐述了目前二维直流电法、瞬变电磁法、三维高密度等超前探测方法的优缺点和在实际应用中的适用条件。根据井下巷道现场工作环境,采用矿井三维高密度超前探测技术、矿井瞬变电磁超前探测技术,对掘进巷道前方断层富水带进行综合探测并对比分析。探测结果表明:三维高密度电法较矿井瞬变电磁方法具有更广的适用性、抗干扰能力;矿井瞬变电磁方法具有较高的低阻分辨能力、一定的探测方向性;两者综合应用于巷道前方构造富水区探测中具有互补性强、精度高等特点。From application theory and implement method , this paper introduced relative merits and adaptability condition of current advanced detection methods including 2-d direct current electric method , transient electromagnetic method , 3-d high-density electrical method.Based on underground roadway environment ,applying mine 3-d high-density electrical advanced detection technology and tran -sient electromagnetic technology , water-rich zone in advance of driving face was comprehensively detected and compared .Results showed that3-d high-density electrical method had wider adaptability and stronger anti -interference ability than transient electromagnet-ic method and the former had higher lowi-mpedance resolution and some-degree detecting directivity .Comprehensive application of the two methods in water-rich zone detection in advance of roadway would exert the advantage of strong complementary and high precision .
