Future underground coal mines will be difficult places for rescue and recovery teams. Such mines will be deeper, gassier, and inherently less stable, and will be located in thinner seams. Such mines will be far greater challenges for successful escape, rescue, and recovery. Rescue and recovery teams will need better equipment and techniques. U.S. Bureau of Mines research is focusing on these problems. Several communication and monitoring systems have been developed. First, a radio communication system has been developed that uses the lifeline as a long antenna for voice communications anywhere along the line and for short distances away from it. This gives the team communications flexibility not possible with sound-powered phones. Lighter, longer lines can be used that need not be recovered. Second, a small portable environmental monitor-telemetry system that uses the lifeline in much the same way has been developed for monitoring the interior of sealed mines. Postdisaster environments often contain high concentrations of toxic or explosive gases in oxygen-reduced atmospheres where conventional sensors do not perform accurately. A novel solution to this problem is presented. Finally a communication interconnect for the outside management and monitoring of in-mine rescue and recovery operations is also presented.
