Wireless Radio System for Underground Mines
Tunnel Radio of America says it has received approval from the Mine Safety and Health Administration (MSHA) for its UltraComm radio VHF and UHF systems and integrated data networks. These technologies provide a wireless environment within an underground mine, allowing operability of modern two-way radios and data systems. The approval includes an U/G power supply with battery backup and an IS supply for the radio network in an X/P enclosure. The company said the network is compatible with its new MineAx wireless tracking system that allows the use of wireless tracking readers. These readers can be deployed at any location in the mine provided with UltraComm wireless as used for two-way radio, so only one wireless backbone network is required for two-way radio and tracking. Readers are independent devices relaying personnel and asset tag input via radio or Ethernet connectivity to capture software on the surface. www.tunnelradio.com
