Abstract: One of the ways to reduce the cost of mining and increase labor productivity at mining enterprises is to increase the energy efficiency of overhead monorails. In the general structure of energy consumption of mining enterprises, electric traction accounts for a significant share making the issue of rational use of fuel and energy resources for traction of mine monorail locomotives relevant. The paper considers the influence of the parameters of a monorail locomotive and its operating conditions on the energy intensity of batteries. A mathematical model and an algorithm for determining the energy intensity of the battery of a monorail locomotive operating both in traction and recuperative modes have been developed, taking into account operating conditions and weight and size parameters. Calculations carried out using the model showed that recuperation is possible when the train moves down an inclined working at angles of inclination of the path over six degrees. It has been established that for a typical scheme of auxiliary transport, consisting of three sections 1.5 km long: two horizontal and one inclined (β = 100), equipped with a MARSHAL battery-powered monorail locomotive, the use of a regenerative drive will reduce the energy intensity of the battery or increase the duration battery life by 13.4%.
