Methods of rational fuel consumption by the dump trucks in deep pits

Abstract

'din, O. V Musikhina, I. A. Glebov The detailed analysis of "consumption Norms of fuel and lubricants..." has been performed. It was approved by the Ministry of transport of the Russian Federation and it is an official document for the valuation and planning of fuel consumption in road transport, including open pits. It was found that the "rate..." was deficient in the specific operating conditions of mining dump trucks and a significant discrepancy with the actual fuel consumption. To the greatest extent, these shortcomings are noticeable in deep pits. In the result of experimental and analytical studies a new method of rationing the diesel fuel consumption of mining dump trucks was developed. It is based on the calculation of fuel consumption for vehicle cycle and bringing the actual path length to the conventional horizontal transportation distances using the criterion of energy. This method requires comprehensive consideration of the design parameters of mining dump trucks -mining and road traffic conditions. As a criterion for evaluating the difficulty of transporting it justifies the use of the coefficient of difficulty of the course, showing how many times the energy consumption in the movement of trucks on the highway exceed the real energy consumption while driving on a horizontal road with the crushed-stone surface of the same length. The formulae are derived to determine the given distance of transportation on the basis of the horizontal equivalent of the vertical movement of the rock mass. It was found that the linear rate of flow of diesel fuel to mileage and transportation work under other equal conditions is determined by two main factors: the distance of transportation of L and the coefficient μ of difficulty of the course. As an example, the calculation of the linear differentiated norms of fuel consumption of dump trucks CAT 785B in an "Udachny" pit AK "ALROSA" (JSC). The developed method provides high accuracy of regulation of diesel fuel consumption in almost any ranges of mining and road traffic conditions and is recommended for use in deep pits.Keywords: dump truck; fuel consumption; given distance; horizontal equivalent of the vertical displacement; the difficulty of the route; quarry.Выполнен детальный анализ «Норм расхода топлива и смазочных материалов…», утвержденных Минтрансом РФ и являющихся официальным документом для нормирования и планирования расхода топлива на автомобильном транспорте, в том числе карьерном. Установлено, что указанные «Нормы расхода…» харак-теризуются недостаточным учетом специфики условий эксплуатации карьерных автосамосвалов и значительными расхождениями с фактическими показателями расхода топлива. В наибольшей степени эти недостатки проявляются в глубоких карьерах. В результате экспериментально-аналитических исследований разра-ботана новая методика нормирования расхода дизельного топлива карьерными автосамосвалами, основанная на расчете расхода топлива за транспортный цикл и приведении фактической длины трассы к условному горизонтальному расстоя-нию транспо...
