- Open pit mine dump trucks with different carrying capacity transport more than 80% of overburden and coal from open pit mines of Kuzbass. The universal indicators of vehicles operating conditions are: energy intensity which determines energy consumption for minerals transportation and durability which characterizes operating life of a unit or an element of a vehicle. Constantly changing mining-geological and mining-technological operational parameters lead to significant costs for diesel fuel and repairing works, planned and unplanned downtime for heavy dump trucks. Therefore, the research, aimed at establishing admittible operating conditions of heavy dump trucks operation in open pit mines, is of current concern. The scientific work is done by means of GPS systems digitized data analysis, and by means of processing the results of experimental tests by methods of mathematical statistics and econometrics. The main results are the following: the effect of average size pieces in the face at energy consumption per unit is estimated; the interconnection of mathematical expectation of stress amplitude occurring in metal structures and energy consumption per unit under rock mass transportation is determined; admittible average diameters pieces of blasted rock mass for dump trucks of different capacity according to operating life criterion of a back axle of a vehicle are defined.
