3.3 Surface mine equipment and process intelligent system planning objectives

(1) Intelligent punching equipment

The manual point lofting method is used in the actual production of most open pit mines, which has the problems of strong subjectivity and imprecise measurement points. Using manual hand-held tape measure to check the drilling quality, repetitive simple labor and low efficiency [22]; Phase I realized real-time collection of rig operation process data, realized digitization of rig operation process, realized automation of some operations, reduced repetitive simple work of field personnel, and realized efficient rig operation; The second phase realizes the remote control and automatic operation of the drilling link, realizes the scientific decision-making of the equipment, achieves the goal of fewer people on the site, and realizes the efficient operation of the rig.

(2) Wisdom of blasting equipment

At present, the best choice of open-pit blasting equipment is the on-site mixed explosive truck, which integrates transportation, production and loading, improving the mechanization and automation level of the production of loaded explosives, and the blasting equipment is developing to the direction of large-scale, information, automation and unmanned. Intelligent blasting equipment will be the development trend and technical research direction of blasting equipment in the future. Finally, the process parameter control and intelligent charging of the charging vehicle are realized, the scientific decision-making of the equipment is realized, the goal of fewer people on site and improving the charging efficiency is achieved, and the efficient operation of the charging vehicle is realized.

(3) Intelligent installation equipment

At present, China's surface mine electric shovel has not undergone information transformation, relatively independent operation, production efficiency is limited by the degree of cooperation between drivers and trucks [94]. The goal of the first phase is to collect the data of the shovel operation process in real time, realize the digitization of the shovel operation process, meet the digital management requirements of the shovel operation, and realize the safe and efficient operation of the shovel. The second phase aims to realize the automatic digging and loading of the electric shovel, improve the working efficiency of the electric shovel, and realize the efficient operation of the electric shovel.

(4) Intelligent transportation equipment

Truck is the main transportation equipment of large open-pit mine, and the advanced open-pit mines at home and abroad all use truck to carry out stripping and coal mining work. At present, China's super large open pit mines such as Heidaigou open pit mine and Yimin open pit mine have implemented digital systems such as truck tire monitoring and management, safety warning system and fuel monitoring. With the development of The Times, intelligent scheduling optimization, truck assisted driving system and unmanned trucks will become the mainstream trend of open-pit truck intelligence. Finally, the real-time collection of truck safety, fuel consumption and tire pressure data is realized to achieve the digitization of the truck operation process, and on this basis, the intelligent scheduling, intelligent assisted driving and intelligent operation of the truck are realized, so as to achieve the goal of fewer people on site and realize the efficient operation of truck transportation.
