Entering the Xishan Coal Dianxianggou Mine dispatching and command center, everyone can't help but be attracted by the 100 square meter screen.On this big screen, you can see all the pictures of underground production.In addition to the real-time picture, the data of mining, transportation and mechanical and electrical engineering are stored and analyzed, and a series of applications in the intelligent control process of coal mine production safety are also clear.
Liu Chenlong, network security administrator of Xishan Coal Power Information Management Department, told reporters: "The Xigou mine has built a ten-trillion industrial network to control data transmission. Do not underestimate this comprehensive control platform. Behind it, there are 27 subsystems running in a centralized way, and there are no longer islands between the systems."
It is understood that the operation personnel of 18106 intelligent fully mechanized mining face in Xuegou mine has been reduced from 12 to 7 people, and the automation rate is stable at more than 85%.After the adoption of intelligence, the coal cutting time of each knife is 1 hour 30 minutes, which is 30 minutes shorter than before.The number of round cuts increases from 8 to 10, and the output of round cuts increases by 3,600 tons.The average monthly advance of 150 meters, the highest monthly advance of 173 meters, to complete 364,000 tons of raw coal output.The supporting coal mining, supporting, transporting and controlling equipment of the intelligent fully mechanized mining face are all first-class equipment in the industry. The shearer and hydraulic support adopt a unified automatic control system, making its intelligent level reach the first-class in China. In March 2022, it was assessed as the first advanced intelligent fully mechanized mining face in Shanxi Province by the Energy Bureau.
Liang Lipeng, director of the electrical Service Center of the mechanical and electrical Department of Xuegou Mine, said: "Compared with manual coal cutting, the intelligent working face can reduce the salary investment of 1 million yuan every year.The automatic coal cutting speed of the shearer is increased to 5 ~ 7m/min, and the raw coal sales of each face can be increased by about 900 million yuan per year. "
If the intelligent fully mechanized mining face is compared to a wing of the inclined ditch mine, the intelligent driving face is undoubtedly another one.The sliding temporary support of intelligent driving face in this mine can realize parallel excavation and support operation and shorten the engineering time.Liang Lipeng said: "Hydraulic bolt drilling car can save 20 minutes per cycle, but also improve the safety of roadway support.Permanent magnet drive belt conveyor belt up to 4000 meters, each shift can reduce 3 belt drivers post workers, transportation efficiency is greatly improved."The working face can be bent two running load belt conveyor and groove belt conveyor lap length up to 15 meters, can meet the production organization of two shifts, greatly reducing the number of pulling the tail.
Xishan Coal Power deeply implements the spirit of "two transformation" conference, promotes industrial transformation by digital transformation, ADAPTS to local conditions, learns from each other, and forms a high, middle and primary three levels of intelligent construction system.At the beginning of 2022, in accordance with Shanxi Province's 2022 Work Plan for In-depth promotion of intelligent coal mine Construction, focusing on the goal of "2025 all large mines and mines with serious disasters become intelligent", Xishan Coal and Power is speeding up the construction of intelligent mines.
"Xishan Coal power to digital transformation to promote industrial transformation, according to local conditions, learn from strengths and weaknesses, intelligent driving face construction to introduce advanced mature equipment and technology, breakthrough industry common difficult problems as a supplement, gradually build Xishan coal power intelligent driving system.""Said Liu Zebang, director of Xishan Coal Power Mechanical and electrical Department.
Since 2020, Xishan Coal Power has carried out in-depth "equipment upgrading, technical support" mechanical and electrical management upgrading action, continued to strengthen the intelligent mine construction, accelerated the "number" and "wisdom" empowerment, through recent years of construction, the initial formation of intelligent fully mechanized mining face construction system has achieved remarkable results, from 2021 to 2022, A total of 23 intelligent fully mechanized mining faces and 38 intelligent driving faces have been built.Compared with previous fully-mechanized mining faces, intelligent fully-mechanized mining faces reduce workers by about 40% and increase production capacity by about 30%, contributing to the normal supply protection situation.
