Results of Pilot Runs in Slicing Mining bySurface Miner Wirtgen 2200SM in the Pyatovskoe Deposit of Construction Limestone

The article presents the results of pilot production of limestone bynon-blast slicing using Wirtgen Surface Miner model 2200 SM in the pit of the Pyatovskoe deposit of construction limestone. The tests, that included stop-watch reading, were used to work out the most efficient procedure of mining using this surface miner, determine its output capacity at various operating modes, study its performance parameters .
