On June 6th, the kick-off meeting and implementation plan review meeting of the national key R&D plan "Large-scale mine comprehensive tunneling robot" was held in Shanxi Coking Coal, marking the official landing of the project in Shanxi Coking Coal. As one of the three coal mine robot projects in 22, the national key research and development plan "Intelligent Robot" supported by the Ministry of Science and Technology, it is planned to complete the research and development in three years. After the successful research and development of the project, it can effectively alleviate the tension of improving coal mining connection, realize the organic integration of big data, artificial intelligence, coal mining and safe and efficient mining, and effectively liberate front-line tunneling workers from the most difficult and safe working environment without absolute guarantee, so that miners can work and live more decently, which is of great and far-reaching significance for promoting the transformation of coal mining methods and the comprehensive reform of Shanxi Province.
energy will continue to play a vital role in the development of China's national economy. Because China has not yet completed industrialization, the level of urbanization will continue to improve, and the level of electrification still has a lot of room for improvement, and it is still in the most vigorous stage of energy and raw material consumption. Among them, coal is an important energy source for China's urbanization construction. In 22, the national coal consumption will be about 4.1 billion tons, up .9% year-on-year. It is estimated that coal will still account for more than 4% of China's primary energy consumption in 235. Therefore, for the coal industry, China has been committed to promoting intelligence, resolving excess capacity and improving energy utilization.
coal mine intelligence is the technical support for the high-quality development of coal. China's coal mining technology has experienced four main stages: manual blasting mining, general mechanized mining, comprehensive mechanized mining and current intelligent mining. Intelligent coal mine is the fourth major technological change in the coal industry.
Coal mine robot is the key link to promote the intelligence of coal industry. The Catalogue of Key Research and Development of Coal Mine Robots divides coal mine robots into five categories: tunneling, coal mining, transportation, safety control and rescue. During the "Thirteenth Five-Year Plan" period, China has eliminated about 1.7 billion tons of backward production capacity. Facing the intelligentization of coal mines, we have carried out special projects such as "Large-scale mine comprehensive tunneling robot", "Coal mine auxiliary transportation robot with complex geological conditions" and "Application demonstration class of anti-scour drilling robot for mine with rock burst", which has achieved certain results and standardized some indicators.
At the beginning of 219, the Catalogue of Key R&D of Coal Mine Robots was published, and it was proposed to focus on key positions and dangerous positions, and focus on promoting R&D of 5 categories and 38 kinds of coal mine robots. With the introduction of national policies, many scientific research institutions, coal enterprises and robot manufacturing enterprises began to explore the development of underground robots in coal mines.
in the new development period of the 14th Five-Year Plan, China has put forward new development requirements for improving energy efficiency, and the relevant special directions have also been adjusted to some extent.
in March, 22, the National Development and Reform Commission and other eight ministries and commissions issued the Guiding Opinions on Accelerating the Intelligent Development of Coal Mines (hereinafter referred to as "Opinions"), which put forward new directions and new conditions for the intelligent development of coal mines, and once again emphasized the goal and task of continuously deepening the intelligent development of the coal industry.
the "opinion" points out that coal mine intelligence is the core technical support for the high-quality development of coal industry, and it is necessary to deeply integrate artificial intelligence, industrial internet of things, cloud computing, big data, robots and intelligent equipment with modern coal development and utilization, and finally form an intelligent system with comprehensive perception, real-time interconnection, analysis and decision-making, autonomous learning, dynamic prediction and collaborative control, so as to realize coal mine development, mining (stripping), transportation and collaborative control. This integrated and intelligent development direction is of great significance for improving the safety production level of coal mines and ensuring the stable supply of coal.
on April 6th, 221, Anbiao National Center for Safety Signs of Mining Products Co., Ltd. (hereinafter referred to as Anbiao National Center) issued the Management Plan for Safety Signs of Underground Robots in Coal Mines and Basic Safety Requirements for Underground Robots in Coal Mines (for Trial Implementation), and put forward safety requirements for robots in coal mines. The relevant requirements were further clarified and the standards were continuously improved.
at present, some coal mines in China are carrying out intelligent construction, but there are some problems such as lagging research and development of basic theories, imperfect technical standards and norms, insufficient platform support, insufficient technical equipment guarantee, and lack of high-end talents.
at the same time, from the market demand, policy demand and technical requirements, it is also very difficult to popularize and apply coal mine robots. From the demand side, the occurrence of coal mine disasters is not a normal event in coal mines. Some intelligent robots are used less frequently and the speed of R&D iteration is not fast, which affects the rescue effect to some extent. Moreover, coal mine rescue robots need professional teams to maintain and train professional operators, and the cost of establishing such a professional team is relatively high. At the same time, policies, laws and regulations on safety licensing, testing and evaluation and standardization need to be more clear, so as to guide the popularization and application of coal mine robots to be more efficient and reasonable.
in addition, technical upgrading is also an important aspect to promote the development of coal mine rescue robots, especially in explosion-proof design, explosion-proof materials, lightweight structure, electronic equipment integration, artificial intelligence and testing methods. These are the problems to be solved in the practical process of coal mine rescue robot. It has been suggested that artificial intelligence technology in other fields can be used for reference and applied to coal mine robots, such as voice recognition and analysis, image enhancement and obstacle recognition, analysis and identification of dangerous gas components, and position navigation based on image features.
In order to promote the high-quality development of the coal industry and promote the transformation and upgrading of the coal industry, the Opinions are divided into three detailed planning objectives:
—— By 221, various types and modes of intelligent demonstration coal mines will be built, and the technical system of information transmission and automatic operation in the main links of coal mine development design, geological guarantee, production and safety will be initially formed, and the number of people in the heading face will be reduced and the efficiency will be improved.
—— By 225, large-scale coal mines and coal mines with severe disasters will be basically intelligent, forming a technical specification and standard system for intelligent construction of coal mines, realizing intelligent decision-making and automatic coordinated operation of pioneering design, geological support, mining (stripping), transportation, ventilation, washing logistics and other systems, robot operation in key underground posts, and intelligent continuous operation and unmanned transportation in open-pit coal mines.
—— By 235, all kinds of coal mines will be basically intelligent, and a coal mine intelligent system with multi-industry chain and multi-system integration will be built, and a coal mine intelligent system with intelligent perception, intelligent decision-making and automatic execution will be built.
Three points are made clear from the goal and path:
1) The vision of coal intelligent development is: to realize real-time perception of multi-source information in coal mine at all time and space, and to control and control the risks in a closed loop, which is intrinsically safe; The whole process of man-machine-ring-pipe digital interconnection works efficiently and cooperatively, and the production site is fully automated, so that coal mine workers have more happiness and coal enterprises have more value creation.
2) The intelligent construction of coal mines should adhere to the classified construction, and take measures according to the mine; Cultivate the typical, demonstrate and lead; Promote in an all-round way and reach the standard by classification; Safety and efficiency, quality first principle.
3) The main path of coal mine intellectualization is "intelligent production decision-making control+robot operation"
At the same time, in December 22, the National Energy Administration and the State Administration of Mine Safety issued a notice on developing the first batch of intelligent demonstration coal mines, and determined 71 coal mines as the first batch of intelligent demonstration coal mines in China, including 66 underground mines and 5 open-pit mines. 63 coal mines were upgraded and upgraded intelligently, and 8 new (expanded) intelligent coal mines were built. The intelligent technical standards for coal mines such as "Technical Conditions and Evaluation of Intelligent Coal Mine Classification and Grading" and "Technical Conditions and Evaluation of Intelligent Coal Mining Face Classification and Grading" have been formulated, and four modes of complete sets of intelligent mining technologies and equipment have been developed, forming a relatively mature intelligent coal mine construction promotion mode.
It can be predicted from China's energy structure that it will be difficult for coal to be replaced on a large scale for a long time to come. At the same time, under the background of the turbulent international political situation and the prevalence of international trade protection measures, coal will remain a "ballast stone" for the safe and stable supply of energy and a "stabilizer" for the adjustment and transformation of energy structure for a long time to come.
However, under the general requirement of carbon neutrality in peak carbon dioxide emissions, the mode of coal production and utilization also needs to be transformed, taking the fourth coal technology revolution as an opportunity to transform into digital and intelligent new industries and new formats. Facing the goal of carbon neutrality in peak carbon dioxide emissions, the energy development during the 14th Five-Year Plan period needs to fully implement the new energy security strategy of "four revolutions and one cooperation" and firmly follow the road of intelligent, green and sustainable development. As a basic energy source in China, the high-quality development of coal is of great significance.
as the core technical support for the high-quality development of coal industry, coal mine intelligence is a new stage of comprehensive mechanization and informatization development in coal mines, a new direction of coal productivity and production mode revolution, and the "fourth important technological change". Accelerating the intelligent construction of coal mines, building a new system of intelligent and green coal mine industry, and realizing the intelligent, safe and efficient mining and clean utilization of coal resources are the only strategic tasks for the high-quality development of China's coal industry in the new period. Promoting the transformation of coal development and utilization mode is also an important measure to realize coal carbon emission reduction, build a clean, low-carbon, safe and efficient energy system, improve the quality of energy supply, and strive to achieve the long-term goal of carbon neutrality in peak carbon dioxide emissions in 23 and in 26.
I hope that more people can participate in the construction of coal mine robots in the future, so that technologies such as artificial intelligence, cloud computing, Internet and big data can escort the coal mine industry.
