It is reported that in recent years, the Ministry of Emergency Management, the National Mine Safety Supervision Bureau seriously implement the CPC Central Committee, The State Council decision-making and deployment, in-depth implementation of the 2020 national coal mine intelligent construction site meeting spirit, promote the mine intelligent construction to make new progress and breakthroughs.According to statistics, at present, there are 813 intelligent mining working faces in The country, and 29 kinds of coal mine robots have been applied in more than 370 mines. With the strong promotion of intelligent construction, the number of coal mine operators in the country has decreased by 370,000 since 2016.The achievements are mainly highlighted in five aspects: new progress has been made in the number of intelligent working surfaces.At present, the number of intelligent mining working faces in China has reached 813, an increase of 65 percent compared with 2020. Among them, 477 coal mining faces, an increase of 43 percent compared with 2020.The number of excavation areas was 336, an increase of 109 percent compared to 2020.29 kinds of coal mine robots have been used in more than 370 mines.New progress has been made in reducing personnel.Intelligent construction has effectively promoted “one excellent, three reduction”. Since 2016, the number of underground coal miners in China has decreased by 370,000.For example, through five years of construction, Shandong province has reduced the number of people who work hard, tired, dirty and dangerous jobs by 34,000, Henan Province by more than 5,000 and Inner Mongolia Autonomous Region by 4,376.In coal mines such as Mayiliang in Inner Mongolia and Jinjitan in Shaanxi, no more than 80 workers in a single shift have been allowed to go underground, and the number of workers in fully mechanized mining face has been reduced to 3-5.New progress was made in technological innovation.The first full-section rectangular intelligent tunneling machine in China has been successfully developed, with the monthly progress of tunneling capacity reaching 3000 meters, and the intelligent operation of “anchor digging support” has been realized.Independently developed 10 meters of mining height intelligent hydraulic support, reached the world advanced level;Intelligent operating system for downhole exploration and drainage, intelligent anti-punching and pressure relief equipment, intelligent anti-punching and limit system have been applied successively. Drilling robots to prevent outburst and prevent water have been finalized for mass production.The number of driverless vehicles in open-pit coal mines reached 146;Intelligent violation control system has been applied in many coal mines.New progress was made in supporting policy projects.Together with relevant departments, it issued the Guide to Intelligent Construction of Coal Mines (2021 Edition) and the Development Plan of robot Industry in the 14th Five-year Plan;Coordinate the Ministry of Science and Technology and the Ministry of Industry and Information Technology to initiate project research and development of key generic technologies in the process of intelligent construction of coal mines, and plan to invest 460 million yuan.Fourteen provinces (regions), including Shanxi, Inner Mongolia, Shandong, Henan and Shaanxi, have successively issued guidance documents on intelligent construction, providing policy, capital and project support for intelligent construction.New progress has been made in the formulation of standards.To guide and promote the formulation of 92 standards for intelligent control system and intelligent production auxiliary system of coal mines.Guided the establishment of the Mining Industry Group of the Big Data Standard Working Group of the National Beacon Commission, organized the compilation of the Specification for Intelligent Mining Data Fusion and Sharing, and further improved the mine intelligent standard system.Disclaimer: This article is reproduced for the purpose of conveying more information.If the source is wrong or violated your legitimate rights and interests, please contact the author with proof of ownership, we will promptly correct, delete, thank you.Email address: newmedia@xxcb.cn
