[0002] One of the processes for the sales of iron ore concentrate powder in metal mines is shipping. The concentrate storage workshop is the concentrate bin of the filtration workshop. Transport vehicles queue up in sequence and enter through the mine cargo transportation gate, then drive along the internal roads of the mining area into the roads around the concentrate bin of the filtration workshop. The overhead crane grab in the concentrate bin fills the vehicle, and the driver drives back along the original route to the gate for weighing and manual measurement. The above process has problems such as slow data recording and statistics, low work efficiency, and easy mistakes. Moreover, there is no video monitoring system during the vehicle transportation process, and effective supervision cannot be formed. A large number of transport vehicles congested at the mine gate will also cause traffic congestion and affect social traffic. The overall efficiency of the iron ore concentrate shipping is low and no longer meets the overall planning and construction of the current digital mine. There is an urgent need for a more efficient and convenient method for shipping iron ore concentrate powder in metal mines. Based on this, the applicant has proposed a method for shipping iron ore concentrate powder in metal mines to solve the above technical problems. Summary of the Invention
