Pilot testing of surface mining technology for blast-free extraction of dolomites by Wirthen 2200 SM surface miners at Mitino quarry.

 M Pikhler, A. Topolev, R. Morgachev, Yu. Pankevich, M. Pankevich

The authors describe mining and geological characteristics of Mitino deposit, as well as the currently used drilling and blasting technology. They also prove feasible the investigation of opportunities for the application of blast-free mining technology to be implemented with Wirtgen Surface Miners.

The article contains the analysis of the results of pilot tests with Wirtgen 2200 SM surface miners for the implementation of slicing technology of the deposit development. The description is given of test methods and procedures, the technology parameters and the surface miner performance demonstrated in a variety of conditions.
