Abstract

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.

Abstract

The present invention is directed to an explosive composition comprised of heavy ANFO and expanded polymeric beads that have a density that is less than the density of the heavy ANFO. The expanded polymeric beads have a size that is determined or based on the size of ammonium nitrate prills used in the heavy ANFO portion of the composition. In one embodiment, the expanded polymeric beads that are utilized in the composition are at least 70% of the lower limit of the mesh size of the predominant ammonium nitrate prill mesh size. In another embodiment, the expanded polymeric beads are at least 70% of the a size that is related to the average mesh size of the ammonium nitrate prills.
