Cap-lamp and communications support system

A cap-lamp and communications support system, comprising:

• a hard plastic shell (1502) on which are directly mounted an LED lamp (1504) and a rechargeable battery (1506);
• a radio transceiver (1508) mounted to the hard plastic shell and powered by the rechargeable battery, and configured to provide two-way voice, data, and SMS text communications underground in a mine;
• a brim-mounted, air-core vertical magnetic dipole (VMD) antenna (1510) connected to the radio transceiver and capable of coupling radio signals into a mine communications network (1516);
• a passive RFID disk transponder (1512) for providing electronic, wireless identification of a registered miner associated with the cap-lamp;
• and
• a plurality of passive RFID disk transponders (1514) for stationing at fixed, surveyed locations throughout a mine and which are encoded with location information that can be read-in through the VMD antenna and transceiver, wherein such information is interpretable to inform a miner wearing the cap-lamp where they are in the mine.

• a passive RFID disk transponder (1512) for providing electronic, wireless identification of a registered miner associated with the cap-lamp;
• wherein, the transceiver (1508) is configured to periodically burst a radio wave to power-up and then listen to a reply from nearby passive reverse radio frequency identification (RFID) tags (1514) integrated with a lifeline waveguide (109);
• and
• said periodic bursts are detectable by Fox Hunter direction finding antennas when locating downed and trapped miners.
