摘要
介绍应用并行电法采集系统,在卧龙湖矿井103工作面进行底板探测。通过网络并行电法数据体的三维电阻率反演,得到矿井工作面底板下三维空间的电阻率分布特征。在该工作面布置钻孔,在底板灰岩层位中电阻率为70Ω.m以下区域,出水量最大达到60 m3/h。该技术取得了煤矿工作面底板完整三维电场参数与电阻率数据体,客观反映了该工作面内底板的水害空间位置,为该矿井防治水工程提供了准确信息。
This paper introduces the floor detection at 103 working face in Wolonghu Coal Mine by the parallel electrical survey system.With 3D-resistivity inversion technology of the net parallel electrical data,the resistivity distribution 3D mine face floor is got.By boreholes at the working face,the biggest water flow is about 60 m^3/h in the area where the resistivity value below 70 Ω·m in the floor limestone.This technology gets 3D apparent electrical data and resistivity data at the working face floor,the space position of the water disaster at face floor is reflected objectively and offers the accuracy information of the water prevention and cure of the mine.
