摘　　要：对原生煤和碎裂煤进行电阻率测试,结合工业组分和孔隙率等对煤样电阻率及电阻率各向异性系数特征进行分析。研究结果表明:肥煤电阻率大于瘦煤、原生结构煤的电阻率大于同阶碎裂煤、煤电阻率随测试频率增加而减小;原生结构煤电阻率各向异性系数小于碎裂煤;垂向与层理方向间电阻各向异性系数最大,层理方向之间的电阻率各向异性系数最小。Electric experiment was carried out to test their resistivity of primary structural coal and cataclastic coal. The results show that： With the test frequency increases, coal resistivity decreases, the resistivity of fat coal is greater that of lean coal, and the original structure coal is greater than the cataclastic coal;the resistance anisotropy coefficient of cataclastic coal is greater than that of original structure coal; the maximum coefficient lies in the vertical direction, while the minimum in the bedding direction.
