Two-way emergency communications at the working face
Problem
- Shortage of skilled labor inhibits timely extension of leaky feeder
- Extending leaky feeder close to the face results in frequent damage from blasting which then often leads to mine-wide system downtime/imbalance
- Personnel at the working face is unable to send distress alarms or receive evacuation messages
- Personnel working alone at the face cannot periodically confirm everything is OK without walking back into coverage
- Supervisors cannot page personnel
Solution
MineTrax battery-powered wireless networks are ideal for use in the "last kilometer":
- Everybody underground is able to add, move or completely relocate network nodes dynamically
- Only one component is required to extend coverage: MineTrax battery-powered wireless infrastructure nodes. No wires, no connectors.
- 915 MHz RF enables nodes to provide coverage at the working face from afar and non-line-of-sight to avoid blasting
- Local damage does not cause mine-wide downtime
- Remote diagnostics tools from surface quickly identify the location of any damaged node
