New infrastructure is accelerating the layout, and smart mines are the undervalued gold mountain

1 The new infrastructure is accelerating the layout, and the intelligent mine has become a development trend

1.1 Mining to digital intelligent transformation

Intelligent mine is based on the modern intelligent concept, focusing on efficiency issues, safety issues and benefits, and deeply integrating the Internet of Things, cloud computing, big data, artificial intelligence, automatic control, industrial Internet, robotized equipment and modern mining development technologies. Form a complete intelligent system of mine comprehensive perception, real-time interconnection, analysis and decision-making, independent learning, dynamic prediction and collaborative control, and realize the intelligent operation of the whole process of mine development, mining, transportation, sorting, safety guarantee, ecological protection and production management.

The core element of realizing smart mine is to integrate modern information, control technology and mining technology, to find an efficient, safe and environmentally friendly production path behind the complex resource mining information, to carry out the best collaborative operation control of the mine system, and to automatically create a new control process according to the change of geological environment and production requirements.

1.2 Started in the 1990s, it is currently in the stage of local intelligence

China's mining has gone through the development stage of mechanization, automation and intelligence, among which, the intelligent construction of mine is based on the achievements of mine automation, information and digitization.

Combined with the historical background of the development of automated mine, information mine and digital mine, the development of intelligent mine can be roughly divided into four stages.

Includes:

(1) Single-machine automation stage (1990s) : The typical features of this stage are the application of classified sensing technology and two-dimensional GIS platform, the formation of single-machine transmission channel, and the realization of programmable control, remote centralized control operation, alarm and locking.

(2) Integrated automation stage (early 21st century) : The typical features of this stage are the application of integrated platform and 3D GIS digital platform, the formation of high-speed network channel, and the realization of primary data processing, primary system linkage, and comprehensive information release.

(3) Local intelligent stage (from 2010 to now) : This stage is the current stage of China's mines, which has experienced two technical stages: visual remote intervention (1.0 era) and automatic alignment of working face (2.0 era), and is currently in the process of studying towards transparent working face (3.0 era). The typical characteristics of this stage are the application of BIM, big data and cloud computing technology, and the realization of local closed-loop operation, multi-system linkage and professional decision-making.

(4) Comprehensive intelligent stage (future) : The arrival of the era of smart mine 4.0, to achieve the level of transparent mine and whole-mine control coordination.

1.3 Coal mine intelligence has taken the lead in entering the initial stage

The mine structure is complex and can be divided into coal mines and non-coal mines, while non-coal mines can be divided into metal mines and non-metal mines. The types of mines are complex and diverse, but because coal mines and non-coal mines have high similarities in mining, rock drainage, transportation and other key links, there is consistency in intelligent transformation methods. Moreover, coal mines take the lead in intelligent transformation due to low construction difficulty and large market demand.

Development of ordinary coal mines into smart coal mines:

(1) Infrastructure such as intelligent system base stations and remote control platforms are needed;

(2) The need for intelligent transformation or purchase of equipment such as coal machines;

(3) Software and hardware construction such as interactive information platform and data analysis system platform are needed;

(4) Each sub-(sub-) control system and control technology need to be connected and integrated, such as fully mechanized mining subsystem, integrated mining subsystem, safety subsystem, lifting subsystem, etc., to form an intelligent complete set of control system for the entire mine.

It involves more than 90 subsystems, which can be divided into three parts: intelligent production system, intelligent occupational health and safety system, intelligent technology and logistics support.

1.4 Smart mine industrial chain has been comprehensively upgraded and production mode optimized

The industrial chain of the smart mining industry shows a dual trend of improving the suitability of upstream components and increasing downstream demand exponentially.

Upstream is mainly used in the system integration of cameras, explosion-proof computers, explosion-proof frequency converter and other parts and bearings, rubber wheels, housing and other processing consumables suppliers, such as Baosin software; Downstream mainly for coal, non-ferrous metals and other mineral resources mining companies, such as Yangquan Coal Group (Yangquan Coal Industry), Shaanxi coal chemical, China Huaneng, etc.; According to the enterprise scale, production conditions, and IT/OT system construction, the industrial Internet opens up the production, transportation and marketing of mineral resources as well as the upstream and downstream links, and realizes the multi-level optimization of mineral subsystems, overall production, and management of mining groups.
