| 摘 要： | 应用数值模拟方法研究了巷道层测深技术应用的环境及影响因素，分析了断层构造在层测深曲线上的响应特征。结果表明，在煤层为高阻，顶、底板为低阻的情况下，巷道层测深技术对断层构造具有良好的分辨率，并且煤层与其顶、底板的视电阻率差异越大，对断层构造的分辨率越高；煤层厚度和断层与巷道的夹角等因素也对探测断层构造的分辨率有一定的影响。

| Abstract: | By using numerical simulation the paper studied the environments and influencing factors of application of coal seam sounding technique in roadway floor, analyzed the response characteristics of fault in coal seam sounding curve. The results indicated that in case where coal was highly resistant, floor and roof less resistant, coal seam sounding had good resolution for fault, the higher the contrast of apparent resistivity of coal and roof/floor was, the higher the resolution for fault. Coal thickness and the angle between roadway and fault also have effects on resolution of the fault detection. |
