摘要: 通过在鄂尔多斯范家村煤矿已知采空区采用分布式高密度电阻率法进行装置形式、电压等参数试验,并对相应剖面曲线、典型剖面、立体切片等进行了电性响应特征分析,系统分析最佳试验参数和采空区识别特征,用于探测、识别未知采空区。结果表明:通过分布式高密度电阻率法优化试验,并对相应的曲线、二维剖面、三维切片等响应规律分析,形成浅埋深采空区高密度电阻率法精细探测体系,且验证效果较好。

Abstract: Through the parameters such as device form and voltage were tested by distributed high-density resistivity method in the known goaf of a mine in Ordos, the electrical response characteristics of the profile curve, typical profile and stereo slice were analyzed. The optimized test parameters and identification features of goafs were analyzed systematically. The results showed that through the distributed high-density resistivity method was used to optimize the test, the corresponding curves, two-dimensional sections and three-dimensional slices were analyzed to form a feasible and effective detection.
