Abstract (en)
[origin: WO2021001783A1] A method of transporting emulsion explosive vertically includes feeding emulsion explosive into a vertically extending conduit, onto a support member that is located in the conduit such that emulsion explosive is supported on the support member in the conduit. The support member is vertically movable along the conduit at a predetermined, variable, controllable rate of descent. The method further includes moving the support member vertically downward in the conduit at a predetermined, variable, controlled rate of descent, thus transporting emulsion explosive vertically in the conduit.
