摘要: 针对鞍千矿业公司科学配矿需求,建立露天矿多采区协同开采资源配置优化模型。针对矿山实际自然环境和生产限制条件,在掌握矿山各采区品位分布等矿山基本信息的基础上,应用线性规划单纯形大M法解算与3DMine矿业软件相结合,并以鞍千矿为实例,验证该方法的实用性。试验结果表明:矿石破碎站的矿石输出品位稳定在要求范围之内,从而保持了选厂入选品位的稳定,最终实现了提高生产效率,降低了生产成本,提高了选矿工艺流程和设备设施的生产能力,对矿山科学生产具有指导性意义。

Abstract: The optimized ore-blending model via collaborative mining of multiple mining areas in open-pit mine is proposed in accordance with the scientific requirement of ore-blending of Anqian Mining Co,.Ltd..taking the Anqian mine as the study example,combing with the actual natural environment and production restrictions,based on the mine basic information (such as the grade distribution etc.) of every mining areas,the 3DMine software and linear programming simplex big M method are adopted to testify the practicability of the ore-blending optimization model.The test results show that:the output ore grade of ore crushing plant is stabilized within the requirements scope to keep stable of the milling grade of beneficiation plants.Therefore the ultimate goals of improve production efficiency,reducing production cost,improving the production capacity of mineral processing flow and related facilities can be realized effectively.The above analysis results in this paper can provide some reference for the scientific production of mines.
