Optimization of parameters of semi-hard overburden excavation by power shovels in open pit mines in Kuzbass

The article focuses on the efficiency of the truck-and-power shovel system. The main method of the truck-and-power shovel system efficiency evaluation in terms of a specific open pit mine is the cost estimating of mining. The cost estimating criterion per an individual process and a technology as a whole is the weighted average of the size in blasted rock fragmentation. Implementation of this method requires determining the power shovel capacity as function of fragment size in blasted rock mass. This article presents the calculated data on power shovel capacity as function of fragment size in blasted rock mass as a case-study of power shovels with bucket capacity from 6.3 to 55.8 m3 using all known formulas. The capacity–fragment size curves are plotted using different procedures. The calculation analysis shows that each procedure has its own range of use. The values of the power shovel capacity calculated from different formulas sometimes differ more than two times. Optimization of the truck-and-power shovel system parameters requires a universal and generalized procedure for calculating power shovel capacity as function of the weighted-average size in blasted rock fragmentation.

Keywords: open pit mine, power shovel, mining technology, parameter optimization, shovel capacity, blasted rock fragmentation, excavation factor, truck-and-shovel system, Kuzbass.
