摘要
煤矿采区的水文地质条件勘察对于煤矿开采意义重大,充分利用瞬变电磁法对低阻良导体反映灵敏的特点,进行含水层的富水性区域划分,配合利用水文钻探资料进行水文地质勘察,可以全面了解采区的水文地质条件。通过对该区地质与水文地质资料的收集整理,结合瞬变电磁勘探资料进行的综合研究分析,编制了瞬变电磁勘探相关的成果图和参数图,通过分析各种图件对含水层的富水性进行了分区。对比表明,应用电性资料划分含水层的富水性分区与钻探资料能够相互佐证。
Hydrogeology survey of coal mining area has the major significance to coal min- ing. Making full use of the transient electromagnetic method on sensitive characteristics of low resistance, carrying on the division of aquifer and using the data of hydrology drill in hydrogeology survey, the hydrogeological conditions of mining area can be fully under- stood. Through the collection of geological and hydrogeological data, combined with the comprehensive research and analysis of transient electromagnetic exploration data, the drawing and parameter graphs related with transient electromagnetic exploration are com- piled. Through the analysis of all kinds of data for the partition of aquifer, the comparison suggested that the application of electrical division of aquifer partition and drilling data can mutually support each other.
