Following the full-scale tests a Wirtgen 2200 SM Surface Miner was commissioned at the second limestone quarry of the Dubovetskoe deposit. In the course of pilot operation a full time-keeping and measurement cycle was performed, limestone slicing process parameters were set, engineering and operational performance of the miner in conjunction with 30, 42 and 45-t dump trucks were calculated. Limestone yield by size was estimated. Specific consumption of fuel was 0.352 l/t of limestone output, the average hourly fuel consumption was 45 l.
