华银铝土矿三维可视化模型与开采计划优化研究

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

采用3Dmine软件建立了广西华银堆积型铝土矿德保矿区地表三维模型、矿体三维模型,并以此为基础,建立了矿体的三维块体模型。以块体模型为基础,以年运费最低为目标函数,供矿要求、矿体的可采矿量等为约束条件,采用线性规划法对开采计划进行了优化,并编制了德保矿区开采计划。

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.
