提出井下稳恒电流场边界元法正演模型，并引入巷道影响因子函数，用以研究巷道空间对周围电流场分布的影响．数值模拟结果表明，巷道影响与电极和巷道的相对位置有关，导致巷道对底板测深类曲线的影响与对层测深曲线的影响不同；由于巷道影响因子是供电电极距的非线性函数，所以在测深类曲线的定量解释中应考虑巷道影响，而解释矿井电剖面曲线时则不需考虑巷道影响；此外，巷道几何尺寸、围岩导电性对巷道影响因子的大小和变化特征起着决定性作用．
A forward modeling method based on the steady current field in borehole is proposed and the influence factor function of roadway is introduced to study the influence of roadway space on the distribution of surrounding electric field. The numerical simulation results show that the influence of roadway is related to the relative position of electrode and roadway, and the influence of roadway on floor sounding curve is different from that of sounding curve. Because the roadway influence factor is nonlinear function of power electrode distance, The influence of roadway should be considered in the quantitative interpretation of sounding curves and the influence of roadway is not taken into account when explaining the curve of mine electric profile. In addition, the influence of roadway geometry and surrounding rock conductivity on the size and variation characteristics of roadway influencing factors effect.
