RE:RE:RE:RE:JIAMA/MINE/Bore-Hole Drilling!Jiama extended mine life is a must Unmanned rail transportation underground mines The underground electric locomotive unmanned driving system is a comprehensive mine production management system with the goal of improving the transportation efficiency of Jiama polymetallic mine and reducing the number of operators and maintenance costs. The system consists of four parts: production and transportation management platform, data support system, production monitoring system and front-end unmanned operation system. It can realize the functions of ore grade matching, optimal transportation capacity scheduling, unmanned locomotive driving, locomotive safety warning and refined management of data, which improves the efficiency of mining and transportation, reduce production costs and ensure work safety. It is an important support system for building intelligent mines, scientific mines and unmanned mines. 14.879 million yuan was invested in the construction of underground rail unmanned driving system in the middle section of 4,450m and 4,400m.
