An electrically driven, movable underground vehicle and a method for operating the same, includes a chassis with at least two driven drive wheels, an electrical trailing cable for connection to an electrical supply network, an electric drive motor, which is electrically connected to the trailing cable, for driving the drive wheels, and an energy storage unit. The vehicle further includes an auxiliary drive motor with a subsequent hydraulic fluid transmission, a switchgear assembly and a processor for controlling the supply of the electric drive motor and the electric auxiliary drive motor with electrical energy. The drive motor directly drives the drive wheels while bypassing the hydraulic fluid transmission. Also, the energy provided by the energy storage unit is sufficient for driving the drive wheels and for temporarily moving the load-haul-dump machine independently of the supply network.
