A Numerical Simulation of Surface Deformation due to Ore Drawing Perturbation

Article Preview

Abstract:

Based on the feasibility of ore drawing simulation with PFC, a PFC numerical simulation was performed on the surface deformation problem in Jinshandian mine. With PFC numerical simulation software, ore drawing simulations were carried out under four covering layer thicknesses of 15 meters, 20 meters, 25 meters and 30 meters. By comparing the deformations of surface loess layer according to the simulation results of four groups, related equation was obtained.
