DARLOT GOLD MINE VDV LEAKY FEEDER SYSTEM FOR PRODUCTIVITY & BLASTING

MINE: DARLOT
OWNER: HOMESTAKE GOLD
TYPE: UNDERGROUND GOLD
LOCATION: LEONORA, WA, AUSTRALIA

BACKGROUND

With the discovery of further ore deposits and subsequent mine life extension, Darlot required the existing surface UHF system to be complemented with an underground communication system. VDV was chosen because we were able to interface to the existing UHF surface system and provide the technical back up for the VDV to be used for telemetry and remote blasting, as well as standard voice communications.

COMPOSITION

Transmission System with 5km of leaky coax cable underground. 4 channel VDV Headend complete with Eclipse repeaters. 12 x Line Amps 3 x BlastPED LF Receiver/Exploders (to be converted to PED version when PED System installed) Telemetry Modules for fans and vent doors.

DESCRIPTION

The system consists of 5kms of leaky coax. A four channel headend is located near the portal transmitting to u/g and 15 km around the surface. The only part of the existing system that was not replaced was the leaky coax cable and some passive branch units.

JUSTIFICATION

Justification was based on the need to better manage the personnel and equipment as the mine expands. The multi-channel VDV system provides voice and data channels for person to person communications, telemetry control of fans and vent doors, as well as communication for a BlastPED System.
