The accelerated integration of new technologies and traditional industries has helped the mining industry to improve quality and efficiency

Previously, the inspection required two people, with listening sticks, thermometers, vibrometers, and record books, to inspect up to 40 points a day, and the inspection data had to be manually entered into a computer. "At that time, inspection mainly depended on the personal experience of the inspector. After the transformation of '5G+ industrial Internet', we only need to bring handheld terminals, inspection cards and small black boxes, and the inspection results are accurate and fast, and a person can inspect more than 200 points a day." "We have also installed a real-time monitoring app, which will immediately alert the police if there is an abnormal situation, and deal with problems in a more timely manner," Shang said.

At the end of last year, Shengwei Building Materials Group built an intelligent expert self-diagnosis system, which places detection sensors in locations where people cannot reach and conducts "physical examinations" on equipment every five minutes. Wang Yong, general manager of the company, said: "The effect of the '5G+ industrial Internet' transformation was immediate, after the completion of the project, the plant's equipment unplanned shutdown rate was reduced by 70%, and equipment maintenance costs were reduced by 30%."

"In the past, there were a number of fully mechanized mining groups in the mine, the early group was responsible for the exploration of gas concentration, a group was dedicated to monitoring the water intake, and a group was responsible for the operation of hydraulic supports, tunneling equipment, and transmission equipment. Based on 5G technology integration, robots that integrate video, environmental monitoring, inspection circuit equipment and other functions are expected to replace traditional tile inspectors, security inspectors, electrical maintenance and other work groups. At present, due to safety concerns, special work types of workers cannot be easily canceled, but it will help to reduce the workload and reduce the number of people." Jinneng Holding Group information Department director Kuang Tiejun introduced.

"The key to supporting intelligent inspection is the word 'real-time'." Lu Le, director of 5G technology in the energy industry of China Mobile Shanxi Branch, said that the company has specially developed the synchronous timing technology of the underground 5G base station network with an accuracy of less than 100 nanoseconds. "The technology uses the ground as a satellite relay station, which can help Inoue synchronously deliver time underground."

Collaborative work, the whole process sharing, intelligent efficiency

"Bang", a large stone fell from the unmanned transport vehicle, "click" a sound, tearing a gap in the transport vehicle tire. When the normal operation of the equipment encounters an emergency, the automatic driving system immediately gives instructions, and the unmanned transport vehicle with a height of 3.5 meters, a length of 9 meters and a load of more than 40 tons will "obediously" enter the inspection area for inspection. "There's a 10cm gash in the left rear tyre!" Li Mingxin, the driverless vehicle dispatcher of Qianye Cement company, started to touch, "Fortunately, it is just a tire."

More often, Li Mingxin's work place is the mining area information center building. At the click of his mouse, more than 20 driverless transport vehicles in the mine began to move in sync. "The computer in the information center can automatically plan transportation routes, remotely control driverless transport vehicles through 5G signals, intelligent formation, scientific management and high efficiency." Li Mingxin said, "I have been a mining truck driver for many years, cold in winter, hot in summer, and have suffered a lot, and now sitting in front of the computer in the office, a person can manage more than 20 unmanned transport vehicles at the same time, very vigorous!"

In recent years, Qianye Cement has cooperated with China Mobile Henan Branch and Henan Yuexin Intelligent Machinery Co., LTD., using 5G, Internet of Things, Beidou navigation and other technologies to promote the construction of intelligent mines. "We solved the problem of collaborative operation between people and equipment, equipment and equipment caused by untimely signal transmission, and realized the unmanned and remote operation of the whole mining process such as digging, loading, transportation and monitoring, which not only improved the safety and comfort of the operation, but also reduced personnel and improved efficiency simultaneously." Qianye cement general manager Xiao Zhanding said.

From automatic operation to automatic monitoring, the coupling degree of automation equipment is getting higher and higher, and the degree of collaboration is getting higher and higher. Li Shouqing, director of Industrial Internet Division of Shaanxi Unicom, explained: "The main thing is to share. For example, in Jiangjiahe Coal Mine, the original 18 sub-systems now realize the whole process of data sharing, real-time monitoring of the operating status of each system and underground environment data, intelligent analysis of abnormal data and alarm data, and timely push the analysis results to the dispatch command center, further improving the ability of mine production scheduling, emergency rescue, decision-making and command."
