Customer Requirements

The coal mine production and management require that, the underground safety hedge "six systems" should be established and improved. These systems include the monitoring and control system, personnel positioning system, emergency refuge system, compressed-air self-rescue system, water rescue system, and communication system. The requirements for underground wireless communications in coal mines include:

 

  • Explosion-proof security:Stable operation, reliable performance, and explosion-proof and intrinsic safety
  • Mobile communications:Voice, SMS, trunking and data communications, supporting interconnection and interworking
  •  Underground coverage:Applicability in special scenario such as long roadways, multiple layers, and many metallic shields
  • Wireless transmission:High-speed data transmission, meeting the requirement for transmission of video surveillance, positioning and production data
  • Trunking dispatch:Coordinated work and unified dispatch among different types of underground workers and between ground and underground

Solution Description

The underground communications system developed by ZTE Trunking is a mature, stable, reliable, and robust system. The system provides the voice, data and trunking services, which not only meet the current requirement for coal mine communications, but also follow the future development trend of digital coal mines and intelligent mines. It provides users with a unified communications platform, to realize integration between dispatch communications and administrative communications, between underground communications and ground communications, between wired communications and wireless communications, between communications and positioning, and between voice communications and data communications.
