RCT reported it has developed a monitoring system to improve underground mining operations at a gold mine in Western Australia’s Goldfields. The miner approached RCT’s Kalgoorlie-based staff to develop a way to monitor the project’s ore passes, to ensure they did not get blocked by larger rocks during the transfer of material.
The ore passes, which are now used to dump waste, are vertical chutes used by the project’s Epiroc MT6020 haul trucks to dump material to backfill an old stope.
The ore pass monitoring system developed by RCT, consists of a VEGAPULS 69 radar, which spans the 91m deep pass and a VEGAMET 391 measurement display to indicate at what depth a blockage may occur. The display was designed to use its readings to control an associated traffic lamp assembly on the wall of the mine to advise mine staff whether material had been successfully transferred.
Once the system was implemented the mining company introduced a procedure for operators to ensure the traffic lamps changed back to green after tipping to indicate the pass is clear of material.
