Abstract:
A system and method are described for locating and communicating with miners in an underground mine, in which miners carry a battery-powered signal unit with an impact actuator engagable with a wall, floor, or ceiling surface of the mine to transmit acoustic signals through the ground, and actuate controls on the unit to send a predefined message or a specific message via the impact actuator to ground-coupled acoustic receivers coupled with a base station that includes a decoder to determine the message sent by the miner and a location component to determine the miner's location based on the received signals.
