摘　　要：为指导生态脆弱区"保水采煤",掌握土层中导水裂缝带发育高度,采用微电阻率扫描成像技术、物理模拟、数值模拟、钻孔冲洗液消耗量观测等手段综合研究,结果表明:物理模拟、数值模拟辨别出的裂采比为28.1~29.1,微电阻率扫描成像探测出裂采比28.3~28.5,微电阻率扫描成像识别与其他手段所得结果吻合。微电阻率扫描成像技术可推广应用于其他矿区土层中导水裂缝带发育高度的探测。In order to guide the coal mining under water-bering ecologically fragile mining area, the micro-resistivity scanning imaging technique, physical simulation, numerical simulation and the drilling fluid consumption have been applied to show the development law of the water flowing fractured soil layer. The results show that the ratio of the height of the fractured zone to the mining height is 28.1~29.1 by the physical simulation and numerical simulation, and the ratio of the height of the fractured zone to the mining height is 28.3~28.5 by the micro-resistivity scanning imaging technique. The field measurement results are identical with the other methods. Micro-resistivity scanning imaging technique can be applied to detect the development of the height of water flowing fractured zone in the soil layer for other mining areas.
