The reporter learned from the press conference of the National Energy Administration held on the 28th today that the intelligent construction of coal mines in China has been accelerated. Nearly 400 coal mines across the country are carrying out intelligent construction, with a total investment of more than 100 billion yuan, about 47 billion yuan has been completed, and 687 intelligent mining faces have been built, which has played an important role in the safe production and supply of coal last winter and this spring. The relevant person in charge of the National Energy Administration said that coal mine intelligence is the core technical support for the high-quality development of the coal industry, which is of great significance for reducing personnel, increasing safety and improving efficiency in coal mines and promoting the transformation of low-carbon energy. Since 2020, the national energy administration, together with the national development and Reform Commission, the Ministry of education, the Ministry of science and technology, the Ministry of industry and information technology, the Ministry of finance, the Ministry of emergency management and the State Administration of mine safety, has issued the guiding opinions on accelerating the intelligent development of coal mines, established a coordination mechanism for the intelligent development of coal mines, aimed at improving the coal supply capacity and focusing on demonstration projects, While improving the system and promoting the work, the intelligent construction of coal mines has been carried out in an all-round way. The person in charge said that first, improve the system of regulations, policies and standards. Intelligent development has been written into the revised draft of the coal law and the coal development plan of the 14th five year plan, the Interim Measures for the management of intelligent demonstration coal mine construction and the Interim Measures for the management of intelligent coal mine expert database have been issued, and the guidelines for intelligent coal mine construction (2021 Edition) and the administrative measures for acceptance of intelligent demonstration coal mines (Trial) have been issued, It provides a legal and policy basis for the intelligent construction of coal mine. The establishment of intelligent coal mine standard system and framework has promoted the promulgation of 12 national standards, industry standards and group standards, 7 industry standards and nearly 100 group standards. The second is to lead the national intelligent construction of coal mines with demonstration. 71 demonstration coal mines have been selected, with a total capacity of nearly 600 million tons / year and a planned investment of about 15.7 billion yuan. The construction is expected to be completed by the end of 2023. According to preliminary statistics, nearly 400 coal mines across the country are carrying out intelligent construction, with a total investment of more than 100 billion yuan, about 47 billion yuan has been completed, and 687 intelligent mining faces have been built. The "few people patrol and no one operate" intelligent mining faces are moving towards normal application, reducing people, increasing safety and improving efficiency, And played an important role in the safe increase of coal production and supply last winter and this spring. Third, vigorously support the R & D and application of technical equipment. The large section rapid excavation anchor system, rock roadway full section excavation equipment and large inclination mining shield machine have been successfully applied underground, the driverless marshalling of mining trucks in open-pit coal mines has been successfully operated, a variety of new rapid excavation equipment systems have been put into use on site, the application effect of energy-saving transmission technology of large mining equipment is remarkable, and the mine Hongmeng operating system has been released, The construction and application of "coal smart cloud" big data platform, the R & D and application of coal mine robot cluster, and the successful R & D and application of complete sets of technologies and equipment for intelligent fully mechanized mining of hard and thin coal seams have provided core support for the intelligent construction of coal mines. Fourth, establish a coal mine intelligent expert database. The national energy administration, together with the Mine Safety Supervision Bureau, has carried out the collection of coal mine intelligent experts, focusing on coal production enterprises, coal machinery equipment manufacturing enterprises, coal research institutes, colleges and universities, coal industry associations and other units. According to the management method of expert database, 172 experts are selected to be included in the expert database by comprehensively considering the industry influence, professional background, on-site experience and other factors, so as to provide intellectual support for the intelligent construction of coal mine. Fifth, cross-border cooperation has been strengthened. The coal mine intelligent technology innovation alliance and coal machinery equipment intelligent industry alliance have been established. Huawei, Shanxi Province and China coal technology group have established intelligent mine innovation laboratories respectively, jointly developed the "mine Hongmeng operating system" with the national energy group, and established a coal mine corps to support intelligent services. Shandong energy group released the world's first highly reliable 5g private network system for mining, and Xinyuan coal mine has built the country's first 5g coal mine. China University of mining and Technology (Beijing) has specially opened undergraduate majors related to intelligent coal mine construction to cultivate professionals for intelligent coal mine. Sixth, jointly hold a national promotion meeting. In September 2020, the Ministry of emergency management, the national energy administration and the State Administration of mine safety jointly held a national on-site promotion meeting on intelligent construction of coal mines. Relevant leaders of the State Council attended and made an important speech, emphasized the significance of intelligent construction of coal mines, and put forward clear requirements and direction of efforts. In September 2021, the National Energy Administration held a national meeting to promote the intelligent construction of coal mines. Zhang Jianhua, Secretary of the Party group and director general, attended the meeting and delivered a speech, focusing on making arrangements and arrangements for accelerating the intelligent construction of coal mines. The competent energy departments of Shanxi, Shaanxi and Inner Mongolia and representatives of demonstration coal mines exchanged typical experiences. "After two years of exploration and practice, the intelligent construction of coal mine has received extensive response and enthusiastic support from coal enterprises and employees. It is the practical application of scientific and technological innovation in the coal industry and the implementation of the data economy development plan of the 14th five year plan Specific actions. The coal industry has increasingly realized that the intelligent construction of coal mines represents the development direction of advanced coal productivity and is the only way for the industry to move towards higher quality development. " The official said that in the next step, the national energy administration will continue to play the role of the coordination mechanism for the intelligent development of coal mines in eight departments, build a scientific and technological innovation platform, improve the policy and standard system, do a good job in publicity and promotion, and build an intelligent coal mine system with intelligent perception, intelligent decision-making and automatic execution, so as to provide a foundation for the steady progress of "new infrastructure" in the energy field.
