Northern shares of the unmanned mine "Big Mac" in Baotou Steel Test

Recently, the 172-ton unmanned electric wheel mine car of Beizhong Group's northern shares was tested at Baotou Steel Group.

The model of the car is MT3600. The whole car is 13.1 meters long, 6.7 meters wide, 6.8 meters high and 172 tons in weight. It adopts intelligent robot and vehicle wire control technology independently developed by Beijing Tagezhi Zhixing Technology Co., Ltd., which can be smooth and accurate at the mine site. Smoothly complete the reversing position, excavator loading, precise docking, automatic dumping, trajectory operation, and autonomous obstacle avoidance. In addition, due to the dust in the mining area, the conventional camera is difficult to function, and the on-board sensor can rely on the dual guarantee of the laser radar and the millimeter wave radar, so that the unmanned electric wheel mine car realizes 360 degree dead angle perception.

It is reported that after the test is completed and improved, the unmanned electric wheel mine car of the North can realize accurate driving and precise stop of the vehicle, and limit the lateral error and heading error to the centimeter level. At the same time, combined with the vehicle cooperative operation platform, the unmanned vehicle team can realize the coordinated operation, and the vehicle perception, data sharing and global know-how can realize the efficient and safe operation of the mining area.

At present, in the mining of large-scale open pit mines, as the mining depth is lowered year by year, the phenomenon of large slope and many curved roads is gradually increasing, which makes the mining production increasingly difficult. The unmanned operation of the mining area is an effective way to speed up the construction of digital smart mines, which will help to achieve safe production, reduce the cost of labor and vehicle use, and improve operational efficiency. According to the research data, under the theoretical condition of reasonable consideration of relevant factors, 7 unmanned mining vehicles can replace the workload of 9 vehicles, fuel cost is reduced by 6%, tire wear is reduced by more than 7.5%, and the benefits including labor cost are saved. The rate is increased by 49%.
