Not only the electromechanical room is unattended inspection, but also in 5G applications, such as unattended tunnel surface and unattended tunnel. Fully mechanized mining face. Xinyuan Coal Mine is based on the lowest underground 5G network in China at present. It is a 534m underground 5G network dedicated to the "super gigabit up" coal mine, which realizes the intelligent management of coal mine and solves many problems in the coal industry.
In fact, the Shanxi Provincial Party Committee and the provincial government have been promoting the development of 5G + industrial applications and the development of intelligent coal mines. For a long time, it has been in the forefront of the country. Yangmei Group has vigorously promoted the 5G + intelligent construction and preliminarily established the first private 5G coal mine network in a relatively short period of time, creating the development process of 5G + smart coal mine. It has achieved remarkable results and demonstrated the construction of 5G coal mines nationwide.
Innovative 5G intelligent mine construction model
"The replacement of mechanization, reduced automation, intelligence in the Yangmei Group Xinyuan Coal mine general survey room, the big screen on these 15 characters are particularly eye-catching, for these 15 characters, builders do their best.
The construction of Yangmei Group's 5G Underground Network Xinyuan company is a tripartite cooperation between Yangmei Group, China Mobile and Huawei, and research and development work began in September 2019. The opening ceremony was held on June 18.
"Building a 5G system in Xinyuan Coal Mine is one of Huawei's most important projects. . Before the project began, Huawei built a team of more than 200 people. 5G Yangmei Commando equipment is used to develop related technologies and solve the influence of temperature and water on the equipment. You could say that the underground wellbore equipment is tailor-made. "Han Weihai, director of 5G industry in Huawei's Shanxi representative office, proudly revealed.
When 5G technology sinks, explosion-proof problems must be solved first. The base station needs to be as small and as functional as possible. In response to these problems, the three parties jointly established the Xingyuan "5G + Smart Mine" Innovation Laboratory, which solved key problems, innovated and transformed 5G base stations, and successfully developed the world's first 5G mining base station. only the underground PTN ring network is used. It could be the capacity of half a county's 5G network.
"Obviously, it is impossible to pick up satellite signals more than 500 metres underground. Therefore, we specially developed the underground 5G base station network synchronization technology with accuracy less than 100 nanoseconds. "It's one millionth of a second," said Lu Le, director of 5G technology for Shanxi's mobile energy industry.
Lu Le still remembers the concept of building a difficult 5G system: "In 2019, I and several of my colleagues received an order to build a 5G network for Singapore Coal Mine. This is very big because we are number one in the country and there is no precedent to follow. Especially during the epidemic, we were "trapped" in the Xinyuan coal mine for more than half a year, with two points and a line in the dormitory. "
< p> in November 2019, the first underground 5G phone was opened; On January 8, 2020, two national coal equipment safety inspection centers in Shanghai and Changzhou opened 5G test base stations. At the end of April, the base station has completed the coal safety certification of the team and completed the underground network of 5G network...
Now, 5G systems can provide complete as well as complete, effective network services.
5G has revolutionized the traditional underground business model
In recent years, people are not unfamiliar, but what is the experience of 5G? Most people still see the flowers in the fog. Will the construction of private 5G networks produce changes more than 500 meters underground?
Yu Beijian, deputy general manager of Yangmei Group, said that the deep integration of modern ict technology in the coal industry with industrial systems is one of them. Change the important way of coal production technology, and will change the way of coal production.
"I am in the control room of the little train. The working surface of the intake port is normal." On May 27, Xi Shubo, assistant captain of Xinyuan Company, was 534 meters underground. Video calls to the Inoue General Dispatch Office on 5G networks. Due to super gigabit uplink bandwidth, Xinyuan's single station can simultaneously transmit more than 50 channels of 4K high-definition images. You can view an underground well from an "immersive" well and remotely control the underground well.
This time, Singapore Dollar coal Mine has launched three 5G applications, which are used for unattended electromechanical cameras, unattended tunnel working surface and unattended tunnel. Fully processed mining face. The mine performed unattended, automated and visual operations. Among them, in order to solve the problem that the mechanical and electrical equipment in coal mine is easy to break down in the long run, the unattended application of the mechanical and electrical room is designed. From remote monitoring to remote monitoring, the operation mode of underground electromechanical room has been completely overturned. Yuan company really carried out unattended and unattended inspection.
The unattended application of tunnel face solves the problem of high risk factors and high labor intensity of traditional manual operation, and can be used for remote operation of cutting and auxiliary operations to achieve safe and accurate remote control of tunnel operation. The unmanned operation at the fully-mechanized mining front has solved the problems of heavy cable maintenance and frequent signal loss during the operation of underground equipment, providing the remote operators with a high definition operation overview. It can effectively reduce the occurrence of safety accidents in dangerous work area and save a lot of manpower. Material resources.
"In the past, there was a lot of dust. Despite the computerized operations, they need people to monitor them on the spot. Now, they can transmit data to the ground using thermal imagers using 5G technology and technologies such as heating imaging and laser scanning, and extract the carbon with a remote control, "Ji said excitedly.
5G has promoted the transformation and modernization of the mining industry
5G coal mines, only the first. This month it has attracted hundreds of mining colleagues, including Chinalco in Henan and Shougang in Tangshan. So far, people are checking it almost every day.
For the coal industry, downhole 5G is about more than just real-time calls and high-performance video streaming. Definition, but also to deepen the integration with tangible industry, promote the transformation and development of the coal industry, promote the ecological transformation of the coal industry chain.
"5G solves so many problems. You can accurately and clearly obtain environmental video and underground safety production data, and conduct high-speed audio and video calls. Definition and other fast data transfer in this era, we can not be left behind. "A mining company manager said. Virtually every visitor wants to take the initiative to computerize mining.

In March this year, eight departments of energy, including the National Development and Reform Commission and the National Development and Reform Commission, jointly issued the Guidelines on Accelerating the Intelligentization of Coal Mines and the Opinions on Industrialization Development, comprehensively launching the construction of new infrastructure for the coal industry and further emphasizing the promotion of new information technology. New generation products such as 5G and ARTIFICIAL intelligence to help the mining industry transform and improve.
With the successful deployment and application of 5G technology in Xinyuan Coal mine of Yangmei Group, it also marks a key step in the construction of "5G + intelligent mine", realizing the goal of 0:1 and the next step is 1:1. N. Promote the experience of Yangmei Group to the whole Shanxi Province and even use new technologies to promote the intelligent transformation of the industry and the great transformation of the coal industry chain.
As the first pilot area for the transformation and comprehensive reform of resource-based national economy, Shanxi has a strong industrial base and resource advantages, which can deepen the structural reform in the western region. On the energy supply side, model the use of clean and low-carbon energy and promote innovation in energy technologies. In the 5G era, Shanxi will seize the opportunity and grasp the situation. It is planned to build 10 intelligent demonstration coal mines and 50 intelligent demonstration fully mechanized mining working faces within 3 years, basically realizing the development of large-scale coal mines, severely damaged coal mines and coal mines in the province. Other coal mines with conditions within 5 years. Intelligence. By 2030, the province's coal mines will have been basically completed.
As the inspection guests arrived, the country's first smart 5G coal mine, like a spark, gradually turned into a blaze. On the grassland.
