The paper presents analytical formulae of the transportation en- ergy of blasted rock mass depending on the route slopes. The figures are obtained for mining dump trucks with a carrying capacity of up to 55 tons, from 55 to 130 tons and from 130 to 320 tons. In addition, analytical for- mulae are presented for the total destructive energy of the structural section elements of dump trucks depending on the longitudinal slope of the route. The work uses the parameters of crack-like defects that are formed on the rear axle housing component of BelAZ heavy dump trucks. The energy de- pendences of the transportation and destruction processes for mining trucks of various carrying capacities are given. An energy joint diagram has also been constructed, which allows determining the maximum allowable val- ues of the transportation energy of the rock mass and the destruction of the structural section elements for given route slopes.
