Detection numerical simulation research on high density electrical method in goaf
XU Guiwa
Abstract：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.
