Numerical Simulation of Fracture Seepage in Pulang Copper Mine Based on COMSOL
In order to supplement the geological characteristics of Pulang Copper Mine and explore the characteristics of fracture seepage in mining area,the numerical simulation of fracture seepage in Pulang Copper Mine is carried out based on COMSOL software.By means of artificial window method,3D laser scanning method and digital panoramic borehole camera method,the fractrue opening degree,fractrue dip angle and crack distribution characteristics of mining rock mass are investigated.The fracture network model was generated by Monte-Carlo method and the geometric parameters of fracture were derived.The fracture model and seepage numerical simulation were carried out by COMSOL software.The simulation results show that the porosity of the mine area is 2.56%and the permeability coefficient is 6.52×10-8 m/s,which is of great significance to the mining and resource evaluation of Pulang Copper Mine,and provides a reference for the numerical simulation of seepage flow in other similar mines.
