乌山铜钼矿地质资源储量数字化管理系统及应用

Digital management system of geologic resource reserves in Wushan Copper-Molybdenum Mine and its application

矿产资源能够得到合理、科学的利用是坚持矿产资源可持续发展的必要条件。针对地质资源管理具有的动态性、复杂性等特点,乌山铜钼矿借助Surpac软件,通过建立地质资源模型,获得了矿山现有资源储量的空间分布情况、数量、品位及可靠程度;从而为掌握矿山资源储量保有及变化情况提供了依据,并在此基础上开发了地质资源数字化管理系统。数字化管理系统的应用使得供配矿品位波动率降低了50%,采矿损失率和矿石贫化率较计划分别降低了0.47百分点、1.11百分点,采剥计划执行率提升10%,工程应用效果较好,可供同类型矿山参考借鉴。

The reasonable and scientific utilization of mineral resources is necessary for sustainable development.In light of the dynamic and complicated feature of geologic resources management,Wushan Copper-Molybdenum Mine with the help of Surpac software constructed a geologic resource model and obtained the spatial distribution of the existing reserves of the mine,and its scale,grade and reliability.It provide basis to master the preservation and variation status of the mine resources,and based on these,develops digital management system of geologic resource reserves.The application of the system makes fluctuation rate of ore supply and blending grade decrease by 50 %,mi-ning loss rate and ore dilution rate decrease by 0.47 and 1.11 percentage points respectively compared to the plan,and the execution rate of mining and stripping plan increase by 10 %.The industrial application is good and the research can be used as reference by similar mines.
