The high-accuracy numerical simulation results by FEM indicate: the overburden deformation and failure caused by mining lead to fracture and the changes of apparent resistivity in overburden. The affected area is much larger than the actual fracture, nearly twice the fracture area. The most affected area by the apparent resistivity values is the caving zone. The changing ratio can be up to 19%. In the cracked zone, the changing ratio of the apparent resistivity is 10% to 12%.
