Energy Assessment of BelAZ-75131 Gas-diesel Mining Dump Trucks Operation at Kuzbass Open Casts

Abstract

The parameters of the BelAZ-75131 heavy dump truck im- proved model using gas-diesel mixture are given in the paper. The moni- toring analysis of the conditions and operation indicators of BelAZ-75131 heavy dump truck using diesel and gaseous fuels is done. Numerical and percentage values of the replacement of diesel fuel with liquefied natural gas when transporting exploded rock mass are determined; the volume of diesel fuel and liquefied natural gas consumption has been established. The analytical dependence to calculate the cost per unit of energy during trans- portation by mining dump trucks with gas equipment is determined. The energy estimation of diesel and gas-diesel mining dump trucks operation is given.
