(Summary description)In 2001, our company passed the ISO9001 quality system certification, and was awarded the title of "famous trademark of Shandong Province" by Shandong Province Industrial and Commercial Bureau.　　Before that, he had been driving the coal mining machine and the belt along the groove for 12 years. "If the coal machine used in the underground mine was a tractor, then the intelligent control equipment for the coal mining machine he is operating in the underground mine is like a Mercedes-Benz or BMW." The intelligent centralized control center where Dong Hebo is located, in addition to remotely controlling the underground intelligent coal mining face, is also responsible for 21 tunneling face transportation belts, 41 coal transportation belts, 9 underground power distribution stations, and 3 underground pump houses. , The visual control of the main and auxiliary well hoisting system and many up and down equipment, as well as the surface monitoring of the safety monitoring system and the personnel positioning system. A full range of intelligent centralized control covers all production links such as mining, excavation, machinery, transportation, and communication. “We started the construction of smart mines at the end of 2018, and successively built 4 smart coal mining faces, with only 2 people in the working face for inspection, and all the remaining operations were completed in the smart centralized control center, truly realizing centralized ground control production with per capita work efficiency Increased by 9 times." According to Zheng Yongsheng, chief engineer of Zhaizhen Coal Mine, the monthly output of an intelligent coal mining face is about 40,000 tons, which is nearly 30% higher than that of ordinary coal mining face. In addition to the increase in output, the speed and efficiency of coal mining machinery and belt transportation have also been increased, and the efficiency of the entire mine has been greatly improved. In addition, the Zhaizhen Coal Mine has also tested the application of remote-controlled digging machines in tunneling. The first-generation digging machines have initially realized functions such as near-ground remote cutting and remote control cutting. They are remotely controlled for 500 meters in the front and have roadway forming accuracy. Control in the range of 100 mm. At present, the second-generation remote-controlled comprehensive digging machine has also been assembled and is used in 11502W track lanes. Wang Qingfeng, the head of the tunnelling mine, told reporters that they have accelerated the research and application of small shield machines, actively connected with Northern Heavy Industries, formulated an installation plan in advance, and went to the manufacturer to learn about assembly, fittings, transportation, and installation in batches, which were improved in advance. Transportation System. Not only that, the tunneling profession continues to tackle key problems in the integration of tunneling, promotes the application of advanced equipment such as pneumatic networking machines, road repairing machines, etc., to create a "comprehensive excavator + loader + 40T chute + forklift" rapid excavation operation line, which greatly improves the excavation efficiency and excavation Control head-on within 7 people. 　　 "Now I am sitting in the cockpit of the hydraulic tunneling rig, and I can easily tunnel with the touch of a button. It is much happier than before." said Lang Xiushuai, a young worker who operates the anchor cable support robot. The 11502 working face under construction in a comprehensive excavation area of ​​the mine uses an anchor cable support robot and an integral lifting work platform. A drill boom is at least equivalent to the efficiency of two pneumatic bolting rigs, and only one person is required to operate it. . 　　 The construction of "smart mines" introduces new equipment such as intelligent control equipment for coal shearers, anchor rope support robots, etc. The direct result is the reduction of underground personnel. Statistics show that since the advancement of the construction of "smart mines", a large number of workers in the Zhaizhen coal mine have been liberated from dangerous positions and weak periods. The number of single-shift production personnel has dropped from 375 at the beginning of the year to 149, a decrease of 60%. “In the past, at least 17 people were required for a coal mining face, but now only 3 people are needed for an intelligent coal mining face.” Hu Peidong, deputy head of the mine, said that of these 3 people, 1 person is responsible for remotely controlling the shearer on the ground. The other two people are in charge of inspections underground. While reducing the number of underground workers, the mine optimized the formation of a new "4776" labor organization, and the underground
