Aiming at the fracture system of rock mass, a method to calculate the anisotropic permeability coefficient is put forward. The numerical method for calculating the anisotropic permeability coefficient by using the finite difference method and the formula for calculating the permeability of the differential element are given. Based on the actual fracture network system data, The application of this method is discussed. This method can calculate the anisotropic permeability of rock mass based on the known fracture network. By encrypting the mesh, it can better eliminate the effects of fracture non-continuity and can deal with problems such as fissure filling. In addition, the permeability of the fractured rock mass can be analyzed with the change of the size of the measuring window and the continuity of its properties
