Design and Application of Underground Mine Driverless LHD Machines System
With the development of China's mineral resources to the deep development,"high ground pressure,high ground temperature,high well depth,mining disturbance of airspace"and other complex stress conditions and harsh mining en-vironment seriously threaten the safety of underground personnel.The unmanned mining equipment is an effective means to solve the problem of underground safety and efficiency.This paper proposes and implements an unmanned system for the under-ground shoveling machine by combining automatic driving and remote-control technology,which realizes unmanned LHD ma-chines out of the mine in a kilometer-deep shaft.In the application test,the maximum speed of the autopilot in the straight line is more than 10 km/h,the maximum speed of the turn is 3 km/h,the delay of the remote control is less than 10 ms.The system can effectively improve the production efficiency of mines,reduce the risk of safety accidents,and help promote the intelligent transformation and upgrading of mines in China.
