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.

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.
