Shanxi Enterprises Group, Xinkuang, Shanxi Mobile and Huawei jointly launched the 5G application pilot deployment

As an important large-scale coal enterprise in China, Jinneng Holding Group has been committed to accelerating the construction and technological innovation of 5G smart mines, especially in the field of 5G smart remote control of roadheaders. Jinneng Holding Group fully plays the leading role in the industry, actively aggregates industrial resources, and jointly conducts the application pilot of 5G smart remote control of roadheaders with coal machinery manufacturers, mining terminal manufacturers, 5G network solution providers (Huawei) and mobile operators (Shanxi Mobile), forming an innovative cooperation model of "5-party collaboration + 4 major measures", strictly implementing 5G remote control technology innovation + OT adaptation + engineering optimization + network optimization, supporting the commercial testing of 5G smart remote control of roadheaders in Tongxin Mine, achieving a mature commercial standard of less than 100ms remote control delay and 99.99% system reliability, and realizing the real meaning of 5G smart remote control of roadheaders. It is estimated that each excavation face can reduce 6 underground personnel each year, while saving 500 meters of optical composite cable auxiliary material costs, and achieving the goal of mine construction with less people, improved efficiency and increased production.

Tongxin Mine 5G remote tunneling scene

The "Smart Mine Innovation Laboratory" was jointly established by the Shanxi Provincial People's Government, Huawei Technologies Co., Ltd., Jinneng Holding Group, and Shanxi Cloud Times Technology Co., Ltd. Through continuous deepening, optimization, and improvement, the laboratory has comprehensively carried out scientific research in the fields of "coal mine information network", "automation enablement", "intelligent sensing technology", "coal mine big data", and "ecological cooperation". The 5G intelligent remote control released this time is an innovative achievement of the Smart Mine Innovation Laboratory. The tunneling face is the core working face in coal mine production, and it is also the scene with the worst working environment and high incidence of production accidents. In order to achieve the core goals of 5G smart coal mine construction with less people, no people, intelligent production, cost reduction and efficiency improvement, the 5G intelligent remote control of the tunneling machine has always been the most concerned exploration practice of Jinkong Group.

At present, Shanxi Mobile has built 148 5G pRRUs in Tongxin Coal Mine, using moisture-proof, dust-proof, explosion-proof, miniaturized wireless base stations with an uplink and downlink bandwidth ratio of 3:2 to achieve full coverage of the underground 5G network and meet the ultra-large bandwidth requirements of the fully mechanized mining face and the tunneling face. Through network optimization and innovation, the operation control accuracy of underground equipment can be improved from 99.9% to 99.99%. At the same time, the core network UPF sinking + kite solution is adopted, and the business data does not leave the park, the network is disconnected and the business is continuous, and it is truly highly reliable and stable. Tongxin Coal Mine deploys a mine cloud network solution to achieve access to 5G base stations and transmit data back to the ground core network. The network slicing technology is used to ensure the high reliability and low latency of 5G services, and at the same time lays the foundation for the multi-use of the network underground in the coal mine.

At the same time, the complex environment and difficulty of signal penetration faced by the network deployment in the comprehensive mining face, as well as the easy damage of optical fiber due to frequent equipment movement, can be solved through the 5G+ leaky cable solution with fitted coverage, making the cable easy to maintain and providing a better high-capacity and non-switching experience. This lays a good network foundation for the application of 5G intelligent remote control in tunneling.
