Selection of Haulage Fleet at Daisy Milano Gold Mine

In the underground mining industry, one of the long-term operational issues involves longer haulage routes as the mine gets deeper with the life of mine. This longer travel route has a great impact on the productivity and cost of the operation. Choosing the best haulage fleet will result in improved productivity and lower cost per tonne of material moved. For this reason, it has motivated Daisy Milano Gold Mine, owned by Silver Lake Resources, to analyse their current Toro 50 Plus trucks against the Atlas Copco MT5010 truck. During a three month trial of both haulage options, trucking parameters were collected from a specifically designed trucking plod.This research used a time motion study to perform productivity calculations and cost analysis of the two haulage options.Based on the assumptions made in this research, the conclusion is that the Atlas Copco MT5010 should be utilised as the preferred truck option at Daisy Milano. The Atlas Copco MT5010 has a higher average productivity of 254 tkm/hr tonnes kilometre per hour) compared to the Toro 50 Plus with an average productivity of 160 tkm/hr. In terms of cost ($ per tkm) the MT5010 is the cheaper option by over 35 per cent when compared to the Toro 50 Plus ($0.85 versus $1.31).Upprättat; 2014; 20140919 (adrhal)
