Designed for use with the company’s MineAx Bird Dog RFID personnel tracking system, new micro‐technology now makes it feasible to wirelessly deploy a multitude of methane and CO sensors anywhere in a coal mine. For the first time, this critical gas level information can be transmitted wirelessly to the surface from the face or remote bleeder areas.

These sensors may operate for months on battery power. The unit also transmits temperature, humidity and barometric pressure readings, providing atmospheric data helpful in evaluating overall mine ventilation system effectiveness. Incorporating the most advanced digital technology available, MineAx creates a modern laboratory within a mine, according to Tunnel Radio.

With this equipment deployed, mine personnel will finally have the ability to monitor methane liberation in real time in return air courses. The fire boss could theoretically review methane readings from a mobile device before he leaves his house. The MineAx Bird Dog tracking system is already deployed in more than 50 mines in three countries.
