Abstract: The mining vehicle has a carriage, driving equipment for moving the carriage, at least one mining work device, an electric motor for supplying power to the mining work device, a connection for supplying electric power to the electric motor from an electrical network of the mine, and an energy source. The electric motor has at least a primary stator winding and a secondary stator winding galvanically isolated from each other. When the mining vehicle is connected to the electrical network of the mine via the primary stator winding, the electric motor is arranged, at least for a period of time, to supply power to the at least one mining work device and, at least for a period of the time, to supply power via the secondary stator winding for charging the energy source. A method for energy supply of a mining vehicle is also provided.

Abstract: The disclosure relates to a mining vehicle and to a method for its energy supply. The mining vehicle has a carriage, driving equipment for moving the carriage and at least one mining work device. The mining vehicle has a connection for supplying the mining work device from the electrical network of the mine and an energy source for supplying energy to the driving equipment. The energy source is charged by using a generator, and the mechanical energy arranged to rotate the generator is obtained from the electrical network of the mine, whereby the electric energy from the electrical network of the mine is transformed into mechanical energy, which is arranged to rotate the generator.
