METHOD AND ARRANGEMENT FOR SUPPLYING REINFORCING CHARGES TO BOREHOLES

摘要

The present invention relates to a method and an arrangement for, in association with blasting works, guiding of initiating and/or reinforcing charges (5, 12) consisting of solid explosive into the desired position in such boreholes (2) as are subsequently to be charged with pumpable bulk explosive. According to the invention, use is made of the pump hose (1) with which the bulk explosive is to be supplied in order to guide the solid explosive charges into the desired position in the boreholes (2). The invention therefore means that the charging hose, in addition to its ordinary function, is also to be used instead of and as charging rod.
