Abstract: Quarry dump trucks are a key element of the transport system of mining enterprises. Their effectiveness directly affects the cost of mining. One of the most important indicators of operational efficiency is fuel consumption, which reflects the cost of energy per unit of work performed. The energy criterion allows you to take into account not only the volume of fuel consumed, but also the energy losses associated with operating conditions, which makes the calculations more accurate and adaptive. The purpose of this work is to develop a reliable and universal method for determining fuel consumption by heavy-duty dump trucks. As a research method, an analytical method was used: physical laws. Based on reduction of mining and technical parameters of rock mass transportation to a single indicator, which is the route transportation distance reduced to a horizontal equivalent, a method was developed to determine fuel consumption by quarry dump trucks according to the energy criterion (transport work). The given transportation distance takes into account the following parameters: the quality of the roadway, the length and slope of each section of the route, the coefficients of use of the carrying capacity and containers of the dump truck, the efficiency of the engine and transmission. The developed methodology increases the reliability of calculating fuel consumption and can be integrated into an automated quarry control system and used to solve various tasks: rationing fuel consumption for any type of dump trucks, planning mining operations, determining the quality of roads during the shift, etc.

Key words: normalization of fuel consumption quarry dump trucks energy criterion transport work
