The Australian-based company did not identify the mine, but said the fleet that went online included four semi-autonomous Cat D11T bulldozers with Cat Command software and SATS technology - all controlled from a remote command centre.
Wolff partnered with Caterpillar and Hastings Deering for implementing and optimising the technology.
According to Wolff, SATS technology enables one operator to control up to four dozers at a time. Ideal for protecting miners from on-site dangers and environmental hazards, SATS can also eliminate workers' prolonged exposure to noise, vibration and dust.
Other benefits, it said, include up- or downhill tip head push and back stacking applications and shift-long operator efficiency.
