ABSTRACT:
A method is provided for loading upwardly extending boreholes in rock with flowable bulk explosives. An explosives loading pipe, an air exhaust pipe and an initiating booster charge with associated initiator are located in the borehole so that the booster and the pipe ends are located deep within the borehole. The ends of the pipes and the initiator are pressed through one or more channels in a cylindrical plug wedged in the borehole opening. Stemming material is first placed in the borehole through the loading pipe to lie against the plug and thereafter the bulk explosive is introduced to fill the borehole. Entrapped air is exhausted through the exhaust pipe.
