It takes ten years to sharpen a sword and forge a sharp blade.
2065438+091October 26th, 10, CCTV broadcast the report of underground intelligent coal mining face in Tashan Coal Mine, and gave high praise to the intelligent construction of Datong Coal Mine. A stone stirs up a thousand waves. Soon, the news that "the national" Thirteenth Five-Year Plan "scientific and technological key project-150,000-ton intelligent caving mining technology, equipment and demonstration project was successfully put into use in the 8222 working face of Tashan Coal Mine Company of Datong Coal Mine Group" was publicized and reported by CCTV Evening News, China News, People's Daily, Economic Daily, Datong Coal Mine Group and many other mainstream media, ranking first. However, only the coal miners themselves know that ten years' exploration and efforts are behind the successful conquest of the intelligent problem of underground coal mining.
Dating back to 2009, Tongmei Group built the first circular economy demonstration park in the whole coal system-Tashan Circular Economy Park. While the whole industry is amazed, Tongmei people have set a higher goal in their hearts-to realize intelligent mining and build a smart mine.
Tashan Coal Mine and Tongxin Coal Mine, as the leading pillar enterprises of the industry's 10-million-ton mines and Tashan Circular Economy Park, are duty-bound to explore the road of intelligent mining in Tongmei Group, and must try first. At that time, the mining of extra-thick coal seams faced by these two mines was the first time in the world. In this context, it is difficult to engage in intelligent mining. After several years of research and exploration, by 20 14, Tashan Coal Mine has made a major breakthrough in the project of "Research and demonstration of key technologies for intelligent fully mechanized top-coal caving mining in extra-thick coal seams with a tonnage of 10 million tons", which has taken a key step towards intelligence. From August, 2065438 to August, 2006, Tongxin Coal Mine successfully put into use the National Development and Reform Commission's "Ten Million Tons High Efficiency Fully Mechanized Coal Mining Key Technology Innovation and Industrialization Demonstration Project" project, which marked the official completion of the first production face with intelligent level in Tongmei Group and opened up a new path for the coal industry to develop into digitalization, informationization and intelligence.
Technical attack and re-launch
Nowadays, in Tashan and Tongxin coal mines, it is nothing new for employees to sit in the dispatching room and operate shearer to mine coal. Coal miners' long-cherished wish of "sitting in an office to dig coal" has become a reality, thanks to the massive investment of Tongmei Group in scientific and technological research in recent years.
Especially after the new leadership of 20 18 Tongmei Group took office, the concept of "scientific and technological innovation ability is the core competitiveness" was further clarified. From 20 18 to 20 19, the whole group invested more than RMB 10, and won 50 provincial and ministerial science and technology awards successively, including 5 awards. Participated in and undertook three major national science and technology projects, and obtained national patents 138. Among them, intelligent caving technology in extra-thick seam, small pillar mining technology, accurate identification technology of coal gangue and inertial navigation technology of domestic shearer filled the technical gaps in domestic coal industry. These achievements have laid a solid foundation for Tongmei Group to speed up the intelligent construction of mines.
Last year, Tashan Coal Mine undertook the research on the key project of "Research and Demonstration on Key Technologies of Intelligent Fully Mechanized Caving Mining in Ten Million Tons Extra-thick Coal Seam", a key research and development plan in the national "Thirteenth Five-Year Plan" resource field. This project takes intelligent fully-mechanized caving mining in extra-thick coal seams with a capacity of 10 million tons as the core, and takes "intelligent group caving mechanism-intelligent caving method-accurate identification technology of gangue-intelligent caving control technology and equipment-engineering demonstration" as the main line, aiming at comprehensively overcoming "research on the theory and automatic caving mechanism of extra-thick coal seams, intelligent caving process model and method of cooperative mining and caving in extra-thick coal seams, accurate identification technology of gangue in fully-mechanized caving face, and intelligent caving control in fully-mechanized caving face". Several key technologies, such as automatic coal caving system, gangue identification prototype based on hyperspectral and audio vibration, inertial navigation system of domestic shearer and top coal thickness measuring device, have started industrial tests, and achieved expected results, creating favorable conditions for intelligent coal mining technology of Tongmei Group to leap to a higher level.
Upgrade and improve efficiency
What is the intelligent fully mechanized mining face like? The actual effect is the most convincing.
From the first working face to now, Tongxin Coal Mine Company has built five intelligent working faces in five years, and completed the intelligent upgrade from 1.0 to1. The 8 102 intelligent working face being mined now is the first highly integrated and fully automatic small coal pillar working face in China. With the continuous upgrading of intelligent level, the per capita coal output of Tongxin Coal Mine Company has increased from 330 tons to 464 tons per year, and the recovery rate of raw coal has increased by 20.8%. Last year alone, it increased its income by 296.4 million yuan, achieving a "double improvement" in efficiency and effectiveness.
Now, "safety, accuracy and efficiency" has become the knowledge of Tongmei Group about intelligent fully mechanized mining face. Tashan Coal Mine and Tongxin Coal Mine have achieved practical results in intelligent construction, which also makes other production mines follow closely and increases the construction of intelligent working faces. Since the beginning of this year, with the coal group in the process of intelligent construction, good news has been reported frequently: on March 15, the intelligent fully mechanized mining equipment of Dijinwan Coal Company was successfully put into trial operation and put into production on April 30; On August 29th, intelligent fully mechanized mining equipment in Jinhuagong Mine was successfully put into joint trial operation. On September 12, intelligent fully mechanized mining equipment in Majialiang Mine was successfully put into trial operation. On September 20th, the intelligent fully mechanized mining equipment in Majiliang Mine was successfully put into trial operation. At the same time, the intelligent fully mechanized mining equipment in Yanzishan Mine is ready, and the final debugging is being carried out nervously and orderly. By the end of this year, Tongmei Group will have 10 intelligent working faces for production at the same time, and the proportion of intelligent working faces will reach 13.6%.
It is believed that with the continuous acceleration of mine intelligent working face construction, the intelligent level of Tongmei Group will be greatly improved, and intrinsically safe smart mines will spread all over the same coal land, taking the lead in the more intense competition in the energy industry in the future, opening up a new road for the entire coal industry to accelerate transformation and upgrading.
