综合物探技术在矿山水文地质中的应用

Integrated Geophysical Technique's Application in Mine Hydrogeology

综合物探技术作为矿山水文地质勘探中的重要手段,保障了井下的安全生产作业,将地震勘探技术与瞬变电磁技术相结合,对东沟矿水文地质进行了详实勘探。选择DZ04地震时间剖面与TEM04视电阻率断面图为对象,于直地层走向布设5条重合测线,参照其物理特性对水文地质状况进行说明。结果表明:两种物探技术在勘探结果方面实现高度的吻合,富水区域主要集中F3、F5区域,中等富水区域主要集中在F3断层北部和F2断层西部。同时发现对矿区生产造成主要影响的地质构造,有1个陷落柱和9条组合断层。

As the heavy handed mean of mine hydro-geological exploration,integrated geophysical techniqueensures underground's safe operation,seismic exploration technology and transient electromagnetic technologyare combined to make detailed exploration for the Donggou mine hydrogeology.Selecting DZ04seismic timeprofiles and TEM04apparent resistivity sectional drawing as the object,to direct formation to5layout the co?incidence line,and makes description according to its physical characteristics of hydro-geological conditions.The results show that:two kinds of geophysical exploration technology are highly consisted in exploration results,watery areas are mainly concentrated in F3,F5region,medium watery areas are mainly concentratedin the north part of F3fault and west part of F2fault,in the mean time also found that the geological structure mainly caused by impact on mine production has1collapse column and9combination faults.
