掘进头前方的断层破碎带和含水体是矿山巷道的主要灾害，提前对其进行超前探测和预测，为巷道开挖提供可靠的技术支持至关重要。基于电磁感应理论，分析了电流正、负波形的一次、二次场特征，提出了视电阻率变化率超前探测的精细处理方法，并详细介绍了计算公式和步骤。物理模拟实验结果表明，采用一阶视电阻率法可以判断各模块的构造界面，边界误差为5%，精细分析方法确定的水体位置与钻孔结果吻合较好。这说明在区分构造和水异常方面，一阶视电阻率比二阶视电阻率更敏感。然而，本文也提出了一些有待解决的问题。
Fault fracture zones and water-bearing bodies in front of the driving head are the main disasters in mine laneways, thus it is important to perform their advanced detection and prediction in advance in order to provide reliable technical support for the excavation. Based on the electromagnetic induction theory, we analyzed the characteristics of primary and secondary fields with a positive and negative wave form of current, proposed the fine processing of the advanced detection with variation rate of apparent resistivity and introduced in detail the computational formulae and procedures. The result of physical simulation experiments illustrate that the tectonic interface of modules can be judged by first-order rate of apparent resistivity with a boundary error of 5%, and the position of water body determined by the fine analysis method agrees well with the result of borehole drilling. This shows that in terms of distinguishing structure and aqueous anomalies, the first-order rate of apparent resistivity is more sensitive than the second-order rate of apparent resistivity. However, some remaining problems are suggested for future solutions.
