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 %,mining 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.
