In terms of the intelligent construction of mines, Caojiatan Mining (Shaanxi Coal Group, Caojiatan Mining Co., Ltd.) has always been in the forefront of the industry. As a large-scale demonstration project unit developed in accordance with the national coal industry's 12th Five-Year Plan, the company is successively rated by the China Coal Industry Association and the Quality Supervision Center of Construction Projects in Shaanxi Coal Industry as an excellent coal industrial integration project and a high-quality engineering unit of the coal industry. Adhering to its innovative spirit of taking the lead and pursuing excellence, Caojiatan Mining actively responds to the call for intelligent construction of coal mines, and works with China Unicom Shaanxi Branch, Shaanxi ZHIN Technology and ZTE to carry out in-depth cooperation. It adopts ZTE’s 5G iCube cloud network integration solution to jointly construct the 5G intelligent mine communication system and explore the intelligent path of mines.
Massive data is a new challenge faced by the mine industrial network
Traditional mines mainly use 4G cellular network, Wi-Fi and other wireless communication technologies. Due to complex working environment, limited underground space, dusty environment and frequent movement of large equipment, long data transmission latency and damage to optical cables often occur during the work, seriously threatening safe production. With the development of intelligent mine construction, a large number of existing and new cameras, sensors, and controllers all need network access. Network coverage and bandwidth are required to meet the requirements of mass equipment and HD video backhaul, and low latency is required to meet the production control requirements of underground equipment. Therefore, the mining industry network is facing severe challenges. Traditional wireless communication technologies cannot meet the evolution requirements of intelligent mines, and are in urgent need of new generation of wireless technologies such as 5G.
Take the leading to build a digital base for mines by leveraging the 5G iCube solution
To further improve the level of mine intelligence, Caojiatan Mining adopts ZTE’s 5G iCube cloud network integration solution and works together with ZTE to build a digital base for the mine, taking actual problems as the starting point. The core highlights of this solution include the integration of 5G high-bandwidth low-latency communication capability and the powerful computing capability of private cloud-end servers to connect underground links, cloud-end links, and overhead links, and integrate all underground services into a unified framework of communication, computing, and management and control.
In the underground, a large number of 5G communication modules are deployed to provide functional modules such as data access, voice, HD video, unified dispatching and personnel positioning for the systems in the whole mining area. In the cloud, the iCube cloud network cabinet is deployed in the central equipment room, the unified cloud digital base is built, and the dedicated 4G/5G integrated core network, dedicated VoNR/VoLTE IMS core network and 3-in-1 integrated NM system (UME R88) and other basic services are deployed. Above the ground, through the control center, data system, and application center, data can be managed visually. The architecture of the 5G iCube cloud network integration solution is shown in Figure 1.

Moreover, the 5G icube cloud-network solution used by Caojiatan has been fully upgraded from the following five dimensions:
By relying on the 5G digital communication base, Caojiatan Mining has successfully completed intelligent innovation systems such as smart grid maintenance, smart tape detection, automatic drainage control, smart frequency conversion wind supply, and smart auxiliary transportation. All systems operate in good condition.
Comprehensive upgrade assists in the high-quality development of the mine
The successful implementation of the "5G iCube cloud network integration solution" in Caojiatan Mining marks the first integrated deployment of cloud, network, application and maintenance in the industry, which lays the foundation for the continuous intelligent upgrade and reconstruction of the mining area and sets an example for the intelligent construction of other mining areas in China.
Caojiatan Mining always adheres to the innovative development concept, continuously increases the construction of smart mines, promotes the profound change in the production mode of "intelligent, real-time, less-manned, and unmanned," and provides core technical support for intelligent mining of coal resources, intelligent transportation, safe and independent guarantee, and intelligent operation management. Intelligent manufacturing leads the future. ZTE will work with multiple parties to promote the implementation of "5G iCube cloud network integration solution" in more mining areas and to facilitate the national intelligent construction and high-quality development of coal mines.
