The present invention is directed to a mobile platform for the delivery of bulk explosives to a blast hole. One embodiment of the platform provides the ability to obtain weight information relating to the contents of a tank that is associated with the platform and that, in operation, contains either the bulk explosive or a constituent of the explosive. The platform comprises a vehicle with a frame, a tank, a load cell structure for connecting the frame and the tank and providing weight data relating to the contents of the tank, and a suspension system that prevents relative movement of the frame and the tank that could compromise the load cell structure. Another embodiment of the platform provides a tank for holding an explosive composition and a rotary shaft that supports a mixing blade that mixes the explosive composition within the tank. The platform further comprises bearing structure for supporting the rotary shaft that is located to deter any of the explosive composition from entering the bearing. A further embodiment of the platform comprises a conduit structure for discharging a bulk explosive into a blast hole that includes a substantially rigid tube with an outlet port for discharging a bulk explosive into the blast hole. The tube is adapted to rotate about a vertical axis such that the outlet port can be moved towards and away from the vehicle along an arc of less than 180°. In one embodiment, the outlet port can be positioned substantially adjacent to an operator's station to allow an operator to readily view the loading of the explosive into the blast hole.
