An apparatus for protecting a miner from injury by a machine in a mine includes an explosion-proof housing. The apparatus includes a proximity sensing portion disposed in the explosion-proof housing having a magnetic field source which produces a magnetic field that is used to sense a location of the miner relative to the machine. The apparatus includes a wireless communication portion disposed in the explosion-proof housing through which the magnetic field produced by the magnetic field source is changed remotely and wirelessly from outside the explosion-proof housing. A method for protecting a miner from injury by a machine. A system for protecting a miner from injury by a machine in a mine.

Method and apparatus for protecting a miner

A monitor for gases 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.

Gas monitor, system and method sensing two different gases

A communication system in a mine having a data network, a wireless network and a plurality of nodes. A communication node of a data network and a wireless network in a mine. A method for communicating in a mine.

Communication system in a mine, a node, and method

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.

A communication system for allowing personnel in a tunnel below ground to communicate with a location above ground includes a controller disposed below ground in the tunnel. The system includes an uplink portion that sends uplink messages from the controller below ground in the tunnel through earth to above ground. The system includes a downlink portion through which downlink messages are sent from above ground through earth to the controller below ground in the tunnel. The system includes a personnel communication portion through which downlink messages are sent from the controller wirelessly to the personnel as personnel messages and personnel messages are received wirelessly by the controller from the personnel below ground in the tunnel. A controller for allowing personnel in a tunnel below ground to communicate with a location above ground. A method for allowing personnel in a tunnel below ground to communicate with a location above ground.
