Mining Publication: Waveform Generator-Package and Receiver: Mancarried and Helicopter Receiver Portion
The report covers the Man Carried and Helicopter Receiver Portion of USBM Contract H0242010. This portion of the contract consisted of the design and building of 15 mancarried and 5 helicopter receivers used for trapped miner location during a mine disaster. Helicopters are equipped with six-channel receivers and used to detect transmitters carried by miners during a mine disaster. Immediately after a disaster a helicopter is flown over the area and, with the aid of the helicopter receiver, coarse location and the active channels are determined. Final precise location is made with the single-channel mancarried receiver.
