基于综合物探技术的地质构造带探测分析

Exploration and Analysis of Geological Structural Zone based on Comprehensive Geophysical Prospecting Technology

以寺河矿W3308综采工作面为背景,采用巷瞬变电磁法和槽波勘探法对工作面的地质构造进行探测。通过巷瞬变电磁法分析工作面富水区分布情况,得到异常区两处,分别位于切眼附近520?570m处和860?910m处;通过槽波勘探法分析工作面地质构造带,得到异常区6处,3处为断层影响或煤体破碎区,2处为煤体破碎区,1处为赋存有断层或陷落柱。

Taking the W3308 fully mechanized mining face of Sihe Mine as the background,the geological structure of the working face is explored by the methods of transient electromagnetic method and channel wave exploration.The distribution of water-rich area in working face is analyzed by transient electromagnetic method,and two abnormal areas are obtained,which are 520?570m near the cut hole and 860?910m near the cut hole respectively.The geological structure zones of working face are analyzed by trench wave exploration method,and six abnormal areas are obtained,three are fault-affected or coal-body-broken areas,two are coal-body-broken areas,and one is fault or subsidence pillar.
