  Are the working face staff clean and can they be turned on?

  The working face staff has been cleaned and can be turned on.

  Ready to boot.

  [Explanation] In a newly built smart coal mine, the 5G smart remote one-key start function makes it a reality for underground miners to achieve ground "white-collar" work.

In the ground intelligent centralized control center, dozens of large liquid crystal display screens, real-time transmission of images at different points such as underground roadways, electromechanical chambers, coal mining faces, and transport belts are transmitted in real time.

Recently, the reporter went to the Xinyan Coal Mine of the Dongyi Group Coal Gasification Company in Luliang, Shanxi Province, to visit the coal mine's 5G applications underground.

  In the past, the coal industry has made some explorations in the areas of automation, unmanned operation, and intelligent inspection of fully mechanized mining and tunneling faces. However, the transmission link has problems such as difficult wired maintenance, narrow wireless bandwidth, and high time delay. Many systems can only achieve monitoring, but cannot perform real-time monitoring.

The application of 5G technology solves the problem of "stuck neck" in the transmission link, helps transform traditional automation to intelligent control technology, and makes it possible to realize intelligent mines.

  [Explanation] On the 160-meter-deep underground intelligent fully mechanized mining face, the intelligent coal mining system is operating efficiently, and coal is continuously transported to the ground.

The data and images of various underground systems are transmitted back to the centralized control center in real time through the PTZ camera and 5G communication network. If there is an abnormal situation, an alarm will be issued and timely response can be achieved.

  Our 1001 fully mechanized mining face uses this video surveillance technology, which mainly uses this pan-tilt camera to monitor the entire coal mining process of the face.

The pan-tilt camera can achieve a 180-degree rotation angle, and then it can "follow the machine", wherever the shearer goes, it will "follow the machine" where it will follow, and it can realize the automatic switching of the screen, and it can monitor the equipment. state.

  [Explanation] Coal mining workers once endured noise and coal dust, and used their bare hands to operate coal mining machines and hydraulic supports to fight underground. Underground work has always been synonymous with flying coal dust and heavy physical strength.

Nowadays, sitting in the office and tapping the mouse remotely, mining coal with one button, the coal production process is undergoing earth-shaking changes.

  [Concurrent] Mei Jun, Chief Engineer of Xinyan Coal Mine, Lvliang Dongyi Group Coal Gasification Co., Ltd.

  The fully mechanized mining face has changed from three shearer drivers and four hydraulic support workers to only one remote control and one safe inspection. The working environment of “dirty, hard, dangerous and tiring” in the past has changed to Now it can be done by sitting in the dispatching command center in a white shirt.

  [Explanation] Through the explosion-proof 5G mobile phone dedicated to coal mines, Chief Engineer Mei Jun is having a video call with ground personnel, and the picture is clear and smooth.

Behind the underground video call is the strong support of China's 5G technology.

In 2020, Xinyan Coal Mine teamed up with Shanxi Mobile to introduce 5G communication technology and was the first to promote underground 5G communication.

  [Concurrent] Mei Jun, Chief Engineer of Xinyan Coal Mine, Lvliang Dongyi Group Coal Gasification Co., Ltd.

  The application of 5G technology in coal mines will help build intelligent open cooperation in coal mines. Xinyan Coal Mine and Shanxi Mobile will continue to strengthen cooperation, establish technology research institutes, industrial alliances and other communities to continue to promote the intelligentization of coal mines and be a pioneer in the energy revolution. Promote the high-quality development of my country's coal industry.
