This is a case study detailing the application of the temporary rib pillar (TRP) method using WebGen™ to reduce dilution at the Musselwhite Mine, located in Thunder Bay, Ontario, Canada. The mine is 100% owned and operated by Goldcorp Inc. and produces 265,000 ounces of gold per annum.

Boral Petrie Quarry is a Greenstone rock with some strong jointing systems throughout, that at times cause issues with batter angles and hence, front burden on the blasts.

Meandu mine is situated 250km north west of Brisbane in Queensland. The mine currently produces approximately 5 million tonnes of coal per annum for supply to Tarong power station. The record blast was fired on time at 3:11pm Friday the 11th December 2009, and caused no delay to other mining operations at the site. With 1029 detonators, it was the largest single Uni tronic™ blast fired in the world at the time.

The Uni tronic™ Electronic Blasting System was used to fire the modified blast. The blast consisted of 552 holes. Average hole depth was 8m and ANFO was used a bulk blasting agent. The modified design resulted in better surface expression and more excavator productivity which led to significant cost savings on site. Excavator productivity has improved from 876bcm/hr to 1,044bcm/hr which translates into 19.7% increase in productivity. Furthermore, the mine doesn’t require a dozer to rip for the excavator to achieve such high dig rates.
