摘要
以高山煤矿为例,开展了瞬变电磁法勘探的现场试验工作,对勘探所采数据进行了预处理、坏点剔除、滤波、高程校正、反演等工作,结合矿区内相关地质情况,进行了多测道曲线分析、各测线的视电阻率断面分析、各煤层的顺层切片分析、富水性综合分析等资料分析解释工作,查找出中、强富水异常区22个:其中9个强富水区、13个中等富水区;正断层F1、F2、F3均为上盘富水性较强。为现场开采设计和灾害防治提供科学依据。
The field test work of transient electromagnetic exploration was carried out in this paper by taking Gaoshan Coal Mineas an example,and related work such as pretreating,removing singular points,filtering,elevation correction and inversion of datathat was explored,data analysis and interpretation work were performed such as multichannel curve analysis,line apparent resistivitysection analysis,the coal seam bedding slice analysis and comprehensive analysis of water rich property combined with thegeological conditions of the mining.22middle and strong abnormal water zones were find out,and there were9rich water areasand13me-dium water rich areas;F1,F2and F3normal faults were on high water abundance.It provided scientific basis for miningdesign and disaster prevention.
