电法勘探在地质构造富水性探测中的应用

Application of electrical prospecting in exploration of water abundance of geological structure

陷落柱、断层等地质构造的发育往往导致主采煤层上部含水层与各灰岩含水层之间水力的联系,使得在下组煤开采过程中的潜在水害威胁较为严重。在对比研究构造(陷落柱、断层)电法响应特征的基础上,寻找一种有效的电法勘探方法。对资料处理解释的关键环节进行优化,并对构造的富(导)水性进行了验证,资料验证情况良好。结果表明,电法勘探在探测影响煤田下组煤开采的构造(断层、陷落柱)的富(导)水性方面是切实可行的。

Development of collapse column, fault and other geological structure led to hydraulic connection between upper aquifer of main working bed and various limestone aquifers, which had a serious potential threate of water disasters to next group in mining proeess. Based on comparative research of structures （ collapse column, fault ） response characteristics, an effective method of electrical prospecting was needed, which optimized key link of data processing, verified water abundance of structure. It showed that data validation was in a good condition. The results showed that electrical prospecting in deteeting structure of lower eoal mining （ fault and collapse column ） of rich water （ guide ） was feasible.
