Yanzhou Coal Industry Accelerates Intelligent Construction

In recent years, Yanzhou Coal Industry insists on the integration of automation, informatization and intellectualization, speeds up the construction of intellectualized mining face, and creates a number of intellectualized and efficient demonstration mines. Xinglongzhuang Coal Mine and Dongtan Coal Mine have passed the acceptance of national and provincial "mechanized replacement, automated reduction" demonstration mines respectively. It has a long history to explore and practice intelligent mining technology in Yanzhou Coal Industry. In 2004, relying on the core technical advantages of fully mechanized top coal caving and fire prevention, Australia Aosta Coal Mine was successfully acquired and fully mechanized top coal caving technology was successfully applied in Australia. In 2005, the technology of "two-pillar fully mechanized top coal caving hydraulic support" was transferred to DBT Company of German Ruhr Group for a fee, thus realizing the first export of coal mining equipment from China's coal industry to developed countries. A historic breakthrough in technology. Under the core business of Yanzhou Coal Mine Group, Yanzhou Coal Industry aims at improving unit production and unit production, takes "automation, informatization and intellectualization" construction as the carrier, regards "heavy equipment, high reliability, automation, less personnel" as the main direction of intelligent mine construction, and speeds up the research and development and use of key technologies and equipment for intelligent mining. Intelligent mining technology of coal mining face with inertial navigation system as the core is introduced for the first time in our country, and a set of domestic fully mechanized mining equipment is formed, which integrates automatic straightening, communication, video, detection and control. It has been successfully applied in 3-4m coal seam fully mechanized mining face of Huanlongwan Coal Mine in Erdos. The production efficiency has been increased by more than 30%, and won the honor in mid-2018. First Prize for Scientific and Technological Progress in Coal Industry. In addition, Yanzhou Coal Industry has intensified its efforts to develop intelligent mining technology and equipment for thin seams, continuously promoted high-power tunneling technology and equipment, and successfully developed a complete set of automated safe and efficient mining technology and production technology for thin seams less than 1 metre. Through sectional remote control, memory cutting and remote operation, mechanized and automated mining of thin seams containing iron sulfide nodules can be realized. The annual output of the thin seam fully mechanized mining team is 660,000 tons, and the imported 12 high-power rock roadheaders realize the mechanization of rock roadway excavation, with an average monthly single excavation of 120 meters, and the excavation efficiency increased by 50%.

Intelligent work puts forward higher requirements for staff training. In order to speed up the reserve of intelligent mining professionals, Yanzhou Coal Industry has launched a three-year project to improve the quality of all personnel. It is aimed at the main mine managers, mining professionals, mining area (team) leaders, technical managers and technical operators, and organizes the development of intelligent mining, intelligent Foundation and practical operation, and intelligent coal miners. Workshops, tunneling automation, electro-hydraulic control system automation technology, mining electrical equipment seminar training courses, a total of 26 training sessions of 700 people.
