摘要：Using GIS, GPS, GPRS and RFID, a dynamic information management system of digital mining in an open pit was designed and developed.A linear programming model was set up in a practical *** the model, the system can automatically draw up production plan of ore blending well every *** system can monitor and dispatch open-pit trucks and shovels well, and can play back their historical *** can monitor and control the process of mining production in real *** RFID, the system can also count the number of trucks'delivery and shovels'loading *** on real scenes show that the performance of this system is stable and can satisfy production standards of mining in open pits.
