The numerical simulation study of stope optimization of structural parameters

In accordance with sub-Tong Au ore mining area above the actual situation, with the help of three-dimensional visual modeling in DIMINE software and FLAC-3D three-dimensional mechanical analysis software, after using the method of three-dimensional finite element’numerional simulation, Optimization analysis and comparision are made on the five schemes including three kinds of structure parameters and three kinds of mining sequence for the deep stope of sub-Tong Au in different mining periods, through the analysis of the various simulation programs of the stress and displacement changes, it obtains the best structural parameters of mine.
