Abstract

The usual methods of calculating mine electric locomotive haulage are very simple, convenient for operational calculations and for selecting elements during design. With some assumptions in the generally accepted traction calculations, they become quite elementary. The traction calculation is greatly simplified with the introduction of the so-called equal resistance slope, i.e. such a slope of the track at which the traction force during the movement of the electric locomotive in the freight and empty directions is the same. The calculation of the check of traction motors for heating becomes elementary, if we assume that the current strength is directly proportional to the traction force of the motor. Significant simplifications are also introduced into the calculations for determining the elements of power supply networks, converter substations and energy consumption. The simplicity of the calculations is an advantage of the existing methods of calculating underground electric locomotive haulage, especially since in most cases these assumptions and simplifications insignificantly affect the accuracy of the calculation. However, in a number of cases, the existing calculations are incomplete and do not provide a final answer. In particular, this is observed in traction calculations. The task of traction calculations includes determining the elements of the rolling stock of an electric locomotive haulage - the size of the train composition and the adhesion weight of the electric locomotive.
