摘要(Abstract)：

巷道底板浮煤等电性不均匀体及厚度变化是造成煤矿井下电测深曲线畸变的主要因素。通过模型实验研究了温纳偏置电测保法压制浮煤等表层电性不均匀体影响的能力。用感度分析法讨论了表层电性不均匀体产生地电干扰的机制。实测结果表明，该方法改善了电测深曲线质量，有效地提高了电测深法地质应用效果。
he undergroud coal mine electrical sounding curve is often disturbaned by the effect of near -surface electric inhomogeneity. In this paper, many modeling and field results have showning that Wenner offset sounding method can effectively eliminate the disturbance. Moreover the sensitivity analyzing technique has been developed to explain the mechanisms.
