Abstract:Taking the Haikou phosphate rock of the largest open-air phosphate mining company-Yunnan Phosphate Chemical Group Co., LTD (YPC) as engineering background, its mining transport process was studied on the basis of the ore body characteristics of the open pit mine and the specific conditions of mining technology, and combine the mining transport process of the domestic and foreign similar conditions of surface phosphate mine. The results showed that: (1) With the continue increasing of oil prices, energy consumption, labor cost and the transportation distance, the single car intermittent transportation process will gradually be eliminated, the continuous and semi-continuous combined transport process with higher degree of mechanization and automation will be carried out in the deep mining stage. (2) Along with the national requirements on environmental protection is increasingly severe, electric double energy harvesters and pure electric car hydraulic drives are the future development direction of mining transportation equipments. (3) Large scale, digital and intelligent is the ultimate direction of mining transportation equipment in the future. It is also the main direction of mining transport process optimization. Related research could provide technical and theoretical guidance for the selection and optimization of process mining transportation of YPC and a large number of similar occurrence conditions of open phosphorus mines at home and abroad.
