摘要
地质构造问题在矿山开采过程中经常会遇到且会给矿山安全生产造成严重威胁,探明断裂破碎带和其他不良工程地质体对于保障矿山安全具有非常重要的意义。文中以某矿山北矿带-270m分段和-260m中段为研究背景,利用瞬变电磁(TEM)勘探方法对本区地层、岩(矿)石的电学性质,以及3个探测工作面,共36个测点进行了现场探测研究,根据测区导电性来分析该被测的地下区域导电性情况,从而确定被测地层含有断裂破碎带和含水溶洞等,进而对成矿理论以及矿山安全生产等方面提供有力的证据。这说明矿井瞬变电磁(TEM)在矿山能做到一定的超前预测的作用。
The issue of geological formation often appears in the process of mining and probably poses a serious threat to the mining production. Therefore, proving the faulted and shattered zone and some other imperfect geology plays a significant role in ensuring the safety of mining production. This paper, through the method of TEM( transient electromagnetic), under the background of a -270 m segment and -260 m middle segment of the northern belt in a certain mine, discussed the electrical properties of the stratum and rock in the area, and detected 3 working face with totally 36 points. And according to the measured conductivity, it analyzes the conductivity of the measured area underground and draws a conclusion that faulted and shattered zone as well as water cave exactly exists in that stratum, thus providing a powerful evidence for the metallogenic theory and safe mining production., It showed that TEM is able to predict the mining production in advance after research.
