Abstract

A monitor for gases and a mine includes a housing. The monitor includes a battery disposed in the housing. The monitor includes a gas sensor portion powered by the battery and in electrical communication with the battery which detects a first gas and at least a second gas different from the first gas in the mine. The monitor includes an alarm portion disposed in the housing, powered by the battery and in electrical communication with the battery which emits a visual alert and an audible alert when the gas sensor portion senses that either the first or second gas is above a predetermined threshold. The monitor includes a wireless communication portion disposed in the housing, powered by the battery and in electrical communication with the battery and the sensor portion, which sends a wireless signal from the housing that the gas sensor portion has sensed of either the first or second gas. The monitor includes a processor disposed in the housing, powered by the battery and in electrical communication with the wireless communication portion, alarm portion, sensor portion and battery. Alternatively, the monitor includes a terminal portion that has two states, an output configuration state in which an output signal is sent from the processor to a first device, and an input configuration state in which an input signal is received from a second device. A method for monitoring gases in a mine. A system for monitoring gases underground. A method and a system for communicating in a mine. A miner communicator. A method for communicating with a minor. A system for monitoring gases on an oil or gas rig. A remote station. A miner apparatus. A method for a miner. A method for a miner to move through a mine.
