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.

Surface Miners 110 plus noumbers in Indian Coal and Limsetone mines are doing excellent and there is vast scope for its use in India. Recent trials in +80 MPa in Bauxite with surface miners also gave good results.
