Intelligent promotion of high quality development in Tongmei group

Recently, two coal mines and six fully mechanized coal faces of Tongmei group were selected into the construction pilot of intelligent coal mine and intelligent fully mechanized coal face in Shanxi Province, which also proves the remarkable achievements of Tongmei group in accelerating the construction pace of intelligent coal mine, improving the intelligent level of coal mine, promoting the transformation and upgrading of coal industry and high-quality development. What kind of change does the intelligent development bring to Tongmei? Recently, the reporter entered Tongxin mining group to explore the intelligent degree of the operation. When the first-line miner gets on the intelligent housekeeper, with the operator pressing the one key start button on the main control panel, the sound of the slowly starting machine in the comprehensive mining face 50 meters away breaks the silence in the deep stratum, the remote miner moves forward steadily, cuts, pushes and moves the coal smoothly and freely, and the conveyor belt continuously transports the produced coal to the ground. The operator sits in the monitoring center of the chute, controls the comprehensive mining equipment through video, switches all kinds of data on the screen, and grasps the production situation.

Recently, the reporter was in Tongxin mine to personally experience the 8305 intelligent chemical work scene. "In order to make the intelligent operation system to the extreme, we have to constantly transform and innovate to make it more suitable for the underground working environment of the same coal." Tongxin mine manager said. Up to now, the mine has completed the upgrading of intelligent fully mechanized top coal caving operation system seven times in a row, improved more than 30 technologies, such as intelligent pressure compensation of initial support force, coal cutting parameter formulation in triangle area, small coal pillar mining, and ground fracturing control technology of hard roof in coal mine, and independently completed the upgrading of intelligent fully mechanized top coal caving operation system version from 4.0 to 9.6. The cultivation of intelligent housekeeper is not overnight. "From 8202 intelligent fully mechanized working face to 8305 intelligent fully mechanized working face, from the front-line miners to keep up with the technical requirements of intelligent equipment to the intelligent equipment to meet the production requirements of the mine, no one knows the production requirements of Tongxin mine better than us, and to make the most of the intelligent effect, we must tailor our clothes according to their own conditions and have" Tongxin core " ".

Yang Jibiao led the team from small to large, from shallow to deep, and from small to small, first increased the support with the machine to move the adjacent frame to boost the function, to ensure the fast follow the machine to move the frame in place, and then increased the support single point start, password login and other functions, to facilitate the operation of the support In more than one year, 238 technical reforms have been carried out, and Tongxin people have made breakthroughs again and again, truly realizing the goals of "intelligent mining equipment, automatic system operation, unmanned post patrol, visualized equipment monitoring, automatic diagnosis and early warning, and integrated information transmission". Robot miner underground inspection "didi There is a fault at the silo of panel 2. " The intelligent inspection robot sends alarm signal and prompt sound to the monitoring platform in the central control room of the main well, and the belt conveyor stops running immediately. When Wang Jianwei, the belt driver of the main shaft, immediately found that the temperature of a idler near the silo in the second panel area had risen on the computer of the monitoring platform, he immediately called the maintenance worker nearby to repair it, and soon eliminated the fault.

In the belt lane of the main shaft of Tongxin mine, which is hundreds of meters underground, a square looking device with a camera is shuttling back and forth on the ceiling track, instead of manually completing the inspection. This is the upgraded intelligent explosion-proof robot put into use in the main shaft belt of Tongxin mine. It walks along the track, checks the idler, belt and other equipment on the belt conveyor at any time, monitors the cable temperature in the tunnel, and can complete the collection of mobile image and sound at the same time, and then upload the data through the wireless base station in real time, which is convenient for maintenance. In work, as long as the battery life is insufficient, the intelligent inspection robot will start the automatic recharge function and return to the charging position for charging. With the robot miner, the inspector realized the double promotion of production efficiency and safety guarantee. A group of inspectors and operators enjoy the safety, efficiency and convenience brought by intelligence. Gao Yong, a mechanic and electrical equipment maintenance worker, enjoys intelligent service. He found that the hydraulic ram oil cylinder was damaged during the maintenance of the coal feeder equipment in the clean coal bunker, and then he used his mobile phone to scan the two-dimensional code marked on the equipment, and the information of the equipment model, parameters, maintenance conditions, fault prone points and spare parts distribution popped up in an instant. He quickly contacted the second maintenance team to allocate spare oil cylinders of the same model for replacement. From fault detection to precise maintenance, the whole process is completed within half an hour, which is impossible in the past. In the past, to complete the maintenance and inspection of mechanical and electrical equipment, workers need to carry a thick data book every time, which records the model, parameters, service life and other important information of the equipment in detail.

Due to the lack of detailed maintenance and replacement information, during the maintenance and inspection, it may be necessary to put the equipment of the same model together for disassembly and inspection, and then recover again, which consumes manpower and material resources. In 2018, more than ten members of Tongxin mine mechanical and electrical innovation studio developed access database to generate a QR code for each mechanical and electrical equipment. This QR code is like a person's ID card. With a mobile phone scan, all the information of the device is clear at a glance. After each maintenance, input the information such as the fault prone point and maintenance times into the computer program to improve the information of each equipment, and the database will record the key maintenance parts of the equipment intelligently according to the input. In this way, only one sweep is needed, and the equipment situation is clear to the mind. The maintenance workers can flexibly grasp the maintenance time and key hidden danger parts according to the "physical examination report" of the equipment provided by the mobile phone. Taking the transportation and marketing Station of the mine as an example, the maintenance amount of more than 100 equipment that the former 15 maintenance workers can complete now only needs 5 workers to operate.
