摘要

以山西东南部某大型煤矿为例,采用瞬变电磁和直流电法对该矿采空积水区进行探查,通过对已知采空区视电阻率特征的分析,确定了该区二种方法的解释原则,及高低阻异常的阈值。并以采区100线对数据资料进行对比分析,以验证二种勘探方法的解释结果的一致性。依据测区瞬变电磁三维数据体切出的3煤视电阻率平面图,圈定了3煤采空积水区的范围。经钻孔验证,D异常区为3煤采空积水区。
        In a case study of a large coalmine in southeastern Shanxi, the TEM and DC electric method have been used to detect gob ponding area. Through known gob area apparent resistivity features analysis, has determined interpretation principle of the two methods, as well as high and low resistivity anomalous thresholds. Taking the data of line No.100 in winning district carried out comparative analysis, to verify interpretation results consistency from the two methods. According to prospecting area TEM 3D data volume sliced coal No.3 apparent resistivity plan, delineated coal No.3 gob ponding extent. After drilling verification has determined the anomalous region D is coal No.3 gob ponding area.
