The author carries out numerical simulation on the typical goaf models using Res2dmod software. The results show that the detection accuracy not only involves with the goaf depth,the level of resistivity and the distance of the adjacent holes, but also relates to the type of detecting devices and the electrode distance. Through the numerical simulation of high density electrical method in the actual goaf, it proves that combining the numerical simulation technology with the field test results has good reference value for supplementary explaining and accurately determining the distribution of goaf.%利用Res2dmod软件对典型采空区地电模型进行数值模拟，数值模拟结果表明探测精度不仅与采空区埋深、电阻率高低及相邻洞体间距有关，还与所采用的探测装置类型及电极距等因素有关；通过对实际煤矿采空区进行高密度电法数值模拟，证明将数值模拟技术与现场实测结果相结合对于补充解释和准确判断采空区的分布范围具有较好的参考价值。
