Development trend and path analysis of China's smart mine

3.3 Intelligent mining process of mineral resources

It is mainly to realize intelligent control and management of mining production process and production auxiliary process. Mining design and planning should achieve digital and three-dimensional visual management, the main equipment of the mine priority to select highly intelligent equipment, reduce the number of production site personnel, with network connection function, to achieve equipment positioning, status and operation data online collection, and access to integrated monitoring platform, to achieve unified scheduling command or remote visual control. The mining operation scope is standardized and controllable by using 3D virtual electronic fence. The mining transportation system should realize data comprehensive integration with the ore quality detection system, establish ore tracking and ore blending control system, and realize online evaluation of ore quality. Production auxiliary system to achieve remote control, data acquisition and intelligent management.

The special equipment such as drilling, drilling and shoveling used in open-pit mining should realize automatic positioning, dynamic tracking and online fault monitoring and diagnosis, and the crushing equipment can achieve automatic control, remote operation, and collaborative work with the transportation system. Select transport equipment with remote control or automatic driving, as well as anti-collision and early warning, blind area monitoring and other functions, tape transport to achieve automatic start and stop, safety intelligent protection, etc., inspection along the use of robots.

Underground mining excavation, mining and lifting transportation mainly use automation and intelligent equipment, greatly reduce the number of employees, real-time collection and remote monitoring of various equipment operation data, loading, transportation and unloading process automation, vehicles with roadway space detection, collision prevention, early warning functions, linkage equipment should have fault chain stop and automatic centralized control functions.

3.4 Intelligent processing of mineral processing

It mainly realizes intelligent control and management in various production links such as crushing and screening, grinding and grading, sorting and processing, concentrate treatment, tailings concentration and transportation. Through the process model, data analysis, expert decision, machine learning and other technologies to summarize the process law, the whole process of mineral processing production self-adaptive, self-decision-making intelligent control. The selected raw materials have ore blending measures and realize optimized ore blending control to stabilize the grade and properties of raw ore. The recovery component balance analysis system is established in the mineral processing process to achieve dynamic management, with online monitoring and process diagnosis functions, to achieve forecasting and early warning, and to improve resource utilization.

The crushing and screening system should realize automatic centralized control, adopt intelligent identification technology online detection and intelligent decision-making, and reduce energy consumption. Grinding grading should have the ability of automatic control process, to achieve real-time optimization and adjustment of product particle size, as well as media storage and automatic addition system. The control system of sorting processing mainly selects the control parameters and strategies independently according to the process status and raw material characteristics to improve the sorting efficiency and recovery rate, and realizes online detection of each process segment to provide data support for parameter optimization. The auxiliary production facility systems such as transportation, hydrothermal, raw ore silo, powder ore silo, and material yard should realize automatic detection and control, and access the integrated control platform.

3.5 Intelligent resource saving and comprehensive utilization

It is mainly to realize intelligent management and control in the tracking evaluation of mine resource utilization, the recovery of common (associated) raw minerals, and the utilization of waste. Establish an information and intelligent management system for resource conservation and comprehensive utilization, improve the assessment of common (associated) mineral resources and waste resources ⒖⒑  gitoxin Α= ⒐ - (associated) mineral resources and waste utilization and management database, provide statistical analysis of yield, utilization rate and other data, analysis and evaluation of common (associated) mineral utilization and waste reuse from the industrial chain and supply chain Value, to achieve the online management of the mining, storage, processing and utilization process of common (associated) raw minerals, to combine the discharge control of waste water, waste gas, tailings, waste rock, etc. with the production control system, and reduce emissions through production control strategies. The comprehensive utilization process is integrated with the main process of production and processing, and the comprehensive utilization cost is reduced through automatic comprehensive control, information unified management, intelligent scientific matching.
