Henan Energy Coking Coal Group Qianye Cement Mine has an ore reserve of 390 million tons, an annual designed mining capacity of 13 million tons, and a mining service life of 30 years. Yuexin Company is responsible for mining and transportation, deploying 60 pure electric mining trucks, 13 remote control excavators and other equipment to achieve fully unmanned and all-weather operations in open-pit mining shovel loading and transportation.

　　01. Overview of homework operation

　　Yuexin pure electric unmanned mining trucks are concentrated in the eastern mining area of Qianye Cement for routine operations. The road situation in the mining area is relatively complex, including both hardened and non hardened roads, with a total distance of 3km. The pure electric unmanned mining truck has a one-way loading and unloading net weight of 45 tons, and the round-trip transportation time is only 40 minutes without waiting in line for loading and unloading.

　　02. Core advantages of unmanned operation

　　Heavy load downhill

　　During transportation operations in mining areas, pure electric mining trucks convert gravitational potential energy into kinetic energy for recoil electricity. Energy consumption has been reduced by over 30%, greatly saving operational costs.

　　Multiple functions

　　At present, pure electric unmanned mining trucks and remote control excavators are capable of shoveling, transporting, and unloading materials throughout the entire road section, with various functions such as zigzag turning, heavy load monitoring, obstacle parking, automatic avoidance, and intelligent control of tarpaulins.

　　03 Remote Dispatch Upgraded

　　At present, the transportation roads in the mining area have been monitored and covered. Through 5G+and Internet technology, the real-time status of the loading, transportation and unloading ports can be accurately observed. Through an intelligent scheduling system, it is possible to confirm the real-time positioning, status, and fault alarm information of mining trucks and excavators, and to update and estimate the quality distribution of ore in the mining area in real time; Remote task allocation, intelligent grouping and operation, etc. are more intelligent and precise, empowered by intelligence and driven by mining.

　　The Qianye Cement project actively explores and steadily promotes green and low-carbon resource extraction, intelligent technology and equipment, and creates a "new sample" of first-class smart mine construction. In the past two months, the Qianye Green Intelligent Mining Construction Project has received more than 30 visits from provincial and municipal leaders as well as industry colleagues. In the future, Yuexin will continue to use technology as its handle and innovation as its blade to promote information transmission networking, unmanned mining and transportation, and intelligent mining construction, and build more truly zero carbon, smart, green, and unmanned new mines.
