Research on three-dimensional visual model and mining plan optimization in Huayin bauxite mine

The three-dimensional terrain model and ore body models were built by 3DMine software in Debao mining area of Guangxi Huayin karst accumulation bauxite mine. The three-dimensional visual block models were built based on the above models. The mining plan was optimized by linear programming method that annual transportation cost was as the objective function, the requirement of supply ore and minable ore amount were as the constraint conditions. The mining plan of Debao mining area of Guangxi Huayin bauxite mine was drawn up.
