“…When calculating the dump truck bearing capacity corresponding to the recommended number of loading buckets (3)(4)(5), it was estimated that dump trucks with bearing capacity up to 130 t are the most effective for ECG-10 excavators. However, specific energy cost for transportation in this case takes rather high value (1.2-1.5 times higher than in energy selection of excavator-automobile complex), which has a negative impact on all the parameters of motor transport operation.…”

Abstract. Every year worldwide coal mining companies seek to maintain the tendency of the mining machine fleet renewal. Various activities to maintain the service life of already operated mining equipment are implemented. In this regard, the urgent issue is the problem of efficient distribution of available machines in different geological conditions. The problem of "excavator-automobile" complex effective distribution occurs when heavy dump trucks are used in mining. For this reason, excavation and transportation of blasted rock mass are the most labor intensive and costly processes, considering the volume of transported overburden and coal, as well as diesel fuel, electricity, fuel and lubricants costs, consumables for repair works and downtime, etc. Currently, it is recommended to take the number of loading buckets in the range of 3 to 5, according to which the dump trucks are distributed to faces.

Crack Formation in Metal Structures of Heavy Dump Trucks during Operation at Kuzbass Open Pit Mines

The results of crack formation monitoring in metal structures of BelAZ heavy dump trucks during their operation at Kuzbass open-casts are given in the article. Possible causes and areas of the crack-like defects formation during operation of heave dump trucks at depths greater than 300 m are considered. The assembly units and elements of heave dump trucks and the areas of the highest total stresses are determined by solid modeling, strength analysis and monitoring of the condition of metal structures under production conditions. The law of crack length development in the areas of the transaxle-housing component and the fastening of the hydraulic cylinder depending on the number of loading cycles is established. The stresses dependence arising in the structural elements of heavy dump trucks during operation under various loads, on the number of loading cycles to failure, is presented.

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.
