Abstract
A miner communication and locating system is disclosed. Two technologies used in the system include a communicator, and a locator array that may be used with a computer. The communicator portion allows trapped miners to continually signal without physical effort that they have survived a cave-in or explosion in a direct, mechanical, and reliable manner. The locator array receives the communicator signal for use to accurately identify where the survivors are underground, and facilitate their rescue; a computer can be used to calculate the position of the communicator from information provided by a plurality of locators: global positioning system receivers may be used with the locator array.
