Simulation Research on Ore Block Model Building Based on Mechanical Analysis of FLAC3D

Based on powerful simulation ability and calculation function of FLAC3D, in the background of a specific mining engineering project, importance of the preparative work before modeling was studied. The principle and necessity of dividing finite unit grid was analyzed from the point of improving the numerical simulation results. On the basis of analyzing the interface problem between different ore-body and rock-mass, numerical model the mine was built using FLAC3D, and the mechanical simulation was carried out. According to the simulation results, feasibility and accuracy of the numerical model was analyzed.
