Abstract: An explosives delivery vehicle for delivering a booster for initiating an explosion of an explosive material in a hole in a floor of a mine pit to an operative depth in the hole. The vehicle comprises a storage assembly for storing a plurality of the boosters, a booster loading assembly for (i) supporting the booster in a delivery position above the hole and (ii) moving the booster downwardly into the hole and inserting the booster at an operative depth in the hole; and a delivery assembly for transporting the booster from the storage assembly to the loading assembly.

Abstract: An assembly (7) for triggering an explosive in a hole (9) to produce an explosive blast in the hole includes (a) an explosion trigger (15, 19) for triggering the explosive in the hole, (b) a detonation unit body (21) that is configured to be located at or proximate an open end of the hole in an initial position of the assembly in the hole and (c) a trigger cord (31) that is connected to the detonation unit body and to the explosion trigger.

Abstract: A booster assembly (60) for use in a drill and blast operation comprises in co-axial alignment: (a) a booster (65) for initiating an explosion of an explosives material in a hole (90) in a pit floor (91) as part of a drill and blast operation, (b) a spool (63) and a detonation cord (66) wrapped around the spool in a storage position outside the hole and connected to the spool and to the booster, and (b) a stake (61). The spool allows the detonation cord to be unwound from the spool as the booster is moved from the storage position to an operative depth in the hole and the spool remains in the storage position. The stake is provided for locating the spool in the pit floor proximate the hole after the booster is at the operative depth in the hole.

Abstract: An explosives delivery vehicle for delivering a booster (65) for initiating an explosion of an explosive material in a hole (90) in a floor (91) of a mine pit to an operative depth in the hole. The vehicle comprises a storage assembly (10) for storing a plurality of the boosters, a booster loading assembly (30) for (i) supporting the booster in a delivery position above the hole and (ii) moving the booster downwardly into the hole and inserting the booster at an operative depth in the hole; and a delivery assembly (20) for transporting the booster from the storage assembly to the loading assembly.
