Abstract

There is provided an all-electric powered ANFO vehicle. The all-electric powered ANFO vehicle includes a support structure. This support structure includes a first and second section and a steering section. The support structure also includes a lift apparatus configured to deliver explosives to a mine face in a mine tunnel. A self-contained battery module is removably mounted on the support structure. A pair of wheel sets is coupled to the support structure, with each wheel set including two wheels. One wheel of each wheel set is rotably coupled on each side of the support structure. A motor is mounted on the support structure and is coupled to at least one wheel and the battery module. A motor controller, including a DC/AC inverter is coupled to the motor and the battery module.
