Abstract: In view of multiple kinds of minerals participating in ore blending at present in Sandaozhuang open pit, the dynamic management system of ore blending involved Molybdenum and Tungsten in Sandaozhuang open pit has designed and realized using GIS, GPS and GPRS.According to the milling grade of Molybdenum and Tungsten in production process, the system can automatically obtain the grades of ore loaded on the shovel, and realize the automatic generation of everyday ore blending production plan and the intelligent distribution of ore blending task.Experiments on real scenes show that this system's performance is stable, and it can satisfy production request of ore blending in Sandaozhuang open-pit mine.
