Danan Lake No. 2 Mine is located in the Gobi desert, 84 kilometers southwest of Hami City, Xinjiang Province. It is dry and has little rain and a lot of dusty weather. The surface temperature of the stope in summer is nearly 68 degrees Celsius in hot weather, and the surface temperature of the stope in winter can reach minus 30 degrees Celsius in extremely cold weather. In September 2021, the National energy group Guoshen Company started to research the unmanned technology of mining heavy trucks, replacing workers with intelligent equipment to complete transportation operations in dust, high temperature, cold, high-risk and high-intensity working environments to ensure personnel safety.
The robot is the first open-pit mine robot in the general transportation scenario in China, which uses an equipment cabin to replace the traditional cockpit, integrates all hardware, and cancels the pilot-related control facilities. In view of the operation characteristics of stope turbulence and heavy dust, the sensor equipment is optimized, a new operation and maintenance logic and human-computer interaction mechanism are constructed, and the debugging mode, remote control mode and unmanned mode can be switched on demand, and some functions can be remotely controlled through APP.
Guoshen has been continuously promoting the construction of intelligent mines, and has built intelligent systems such as vehicle collision prevention, overspeed warning, coal seam spontaneous combustion warning, video surveillance, and inspection robots, which realize the early warning and monitoring of coal seam high temperature and heat, the full coverage of production sites, and uninterrupted inspection of substation and booster stations. At present, the company is promoting the construction of projects such as research on key technologies for transparent geological support and mining full-life cycle production decision-making, 5G signal coverage, and intelligent integrated management and control platforms.
