摘要
应用矿井音频电穿透技术,对呼吉尔特矿区巴彦高勒煤矿侏罗系延安组3-1煤层顶板延安组砂岩含水层及上部直罗组砂岩含水层进行了探测。物探成果与疏放水工程及回采涌水量对比分析表明:在地层垂向结构相同、横向相对均一的情况下,异常幅值及范围越大,含水层的富水性越强,疏放水量及回采涌水量的大小与音频电穿透异常强度、异常范围正相关。
In Hjert coal mine area bayangaole coal mine the No.3-1coal seam top sandstone of jurassic Yan′ an formation and the Zhiluo formation are mainly aquifer, which has obvious characteristics not only in nonhomogeneity but also in strip chart.It is one of importantwork to detect and dealwith these anomalous geologic body rightly in order to insure safety production and improveproduction efficiencies.Comparative analysis of geophysical results and drainage borehole and discharge rate that when vertical structure of strata is similar and homogeneous in horizon-tal direction,the higher apparent resistivity and higher abnormal range,the more water is contained in the strata.The water yield is correlated to apparent abnormal range and intensity of voice frequency electric perspective.
