Abstract
In 2017, the MICROMINE PITRAM system began to be used in open-pit mining by Erdenet Mining Corporation which allows researchers and production engineers as well as technicians to obtain highly accurate information on the use and technical condition of mining machines and self- propelled equipment in a fairly short time, providing the opportunity to develop scientifically based technical and technological solutions for the company. Due to the change in the mining and technical conditions of the Erdenet ore mine along with an increase in the depth of the mine, the average transportation distance increased to 7-10 km and the increase in the number of mountain boulders, there was a constant need to optimize the mode of technological transport. The fuel consumption for one cycle of transportation of a heavy dump truck is affected by structural, mining, technological, operational and climatic factors. In order to realistically determine the amount of fuel consumed per 1 tonne kilometre (t/km) of transportation by dump trucks in an open-pit environment, based on statistical research and production measurements, fuel consumption and factors affecting it (main road resistance, slope, length, mass, volume of rock) are measured and the relationship between them was carried out by regression analysis. Using the Python programming language, a regression relationship was determined between fuel consumption per 1 t/km of a dump truck and mining and technical factors affecting consumption, such as transportation distance, total resistance to movement and actual load capacity, where they were compared using 2 models: linear and quadratic.
