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

More accurate mining, more efficient detection, easier data sharing... In recent years, "5G+ Industrial Internet" has accelerated the deep integration with the traditional mining industry, forming effective practices in remote equipment control, unmanned intelligent inspection, and equipment collaborative work, promoting the quality and efficiency of the industry, ensuring safe and orderly production, and injecting new momentum into the high-quality development of the industry.

In Shanxi Province Datong Jinneng Holding Coal Industry Group Tashan Coal Mine Co., LTD., 200 meters underground, accompanied by a "buzz" sound, the roller of the boring machine rotates rapidly, the spray spray next to the roller tightly covers the flying debris of the coal seam, large pieces of coal are easily "cut" down, falling on the belt in front. Belt "non-stop", quickly to the top of the channel, after a number of "water curtain hole" (shearer spray dust removal device) washed and "jumping machine" (coal belt cleaner) screening, black shiny coal fell into the container waiting for a long time.

Amazingly, the flow of work down the mine is carried out remotely by an operator in front of an on-board computer. Today's mining industry, through the empowerment of "5G+ Industrial Internet", has significantly reduced cost, improved quality and increased efficiency, and further guaranteed safe production.

Remote operation, safe and accurate, high skill requirements

The operations under the Tashan coal mine are actually actions made under the instructions of the "above" computer. In the command hall on the ground, the staff stared at the large computer screen, the real-time video and indicator data of each channel and machine bayonet were clearly presented one by one, and the phone ringing from the mine also rang from time to time. "The crusher, conveyor and other equipment below are run by instructions from above." Tashan coal mine monitoring center director Zhang Hui said.

Zhang Hui introduced: "Taking a working face in Tashan Mine as an example, in the past, when top coal mining, multiple workers were needed to operate a working face. On a working surface, it is necessary to set 50 to 100 top coal hydraulic supports, each worker according to experience to judge the time, one by one set the hydraulic support parameters, high labor intensity, the working environment is not good. With the fully automated coal discharge system and 5G network that can adjust parameters in real time, 100 hydraulic supports can be lowered at the same time with one person's operation, which is safe and efficient."

With the support of "5G+ Industrial Internet", remote control of machines is not only more efficient, but also more accurate. Guo Yanao, an employee of Henan Coking Coal Group's Qianye Cement company, is now a remote operator. His eyes were glued to the screen, his hands were playing with the joystick from time to time, and the excavator on the screen was working synchronously with his movements. "As an unmanned excavator remote operator, my job is to sit here and remotely control the excavator to pour ore into the truck." Guo Yanao introduced that although the way of working today is different, the new technology puts forward higher requirements for operational skills, and the position of the unmanned transport vehicle and the excavator must be accurately matched, and the error cannot exceed 30 centimeters.

Huawei has partnered with Jinergy Holding Group to set up a mining laboratory dedicated to research. "5G is applied to life, and more meets the downward needs of ordinary consumers." For downhole, there is a large amount of monitoring data upload and a small amount of command down transmission." Zhao Zhipeng, director of Huawei's global 5G Marketing Department, said that to this end, the enterprise has made corresponding adjustments to meet the application needs of industrial upload and control.

Intelligent inspection, the cost is falling, the efficiency is improving

He Junying is a staff member of the mechanical and electrical department of Jiangjiahe Coal Mine of Binxian Coal Co., LTD., Shaanxi Province. Some time ago, he received an intelligent warning from the "Binmei Cloud" big data platform, indicating that there was abnormal vibration in the shaft of the shearer cantilever, and quickly contacted the Shanghai Coal Science Digital Technology Center for data docking with the platform. Through a remote analysis and consultation system, industry experts in Shanghai gave him real-time feedback on diagnosis results and maintenance suggestions.

In addition to downhole, intelligent detection in Wells is also becoming more efficient. In the cement factory of Shaanxi Shengwei Building Materials Group, inspector Shang Yaojun came to a grate cooler and put a small black box on the machine. This black box half the size of the palm of the hand is an intelligent vibration thermometer, only after 1 minute, the temperature, vibration frequency and other information was transmitted to Shang Yaojun's handheld mobile terminal through Bluetooth, and directly uploaded to the enterprise's big data platform.
