Abstract
A method of vertically transporting emulsion explosive includes, using a pump, pumping a predetermined volume of emulsion explosive, from an emulsion explosive reservoir, into a vertically extending pipe, wherein pumping is effected airtightly at least between the pump and a downstream end of a volume of emulsion explosive that has been pumped into the vertically extending pipe for at least a part of the travel of emulsion explosive of the predetermined volume of emulsion explosive down the vertical pipe.

A method of vertically transporting emulsion explosive, the method including, using a pump, pumping a predetermined volume of emulsion explosive, from an emulsion explosive reservoir, into a vertically extending pipe, wherein pumping is effected airtightly at least between the pump and a downstream end of a volume of emulsion explosive that has been pumped into the vertically extending pipe for at least a part of the travel of emulsion explosive of the predetermined volume of emulsion explosive down the vertical pipe, wherein the vertically extending pipe extends vertically for a vertical distance beyond 500 m.
A method of vertically transporting emulsion explosive, the method including, using a pump, pumping a predetermined volume of emulsion explosive, from an emulsion explosive reservoir, into a vertically extending pipe, wherein pumping is effected airtightly at least between the pump and a downstream end of a volume of emulsion explosive that has been pumped into the vertically extending pipe for at least a part of the travel of emulsion explosive of the predetermined volume of emulsion explosive down the vertical pipe, wherein the emulsion explosive is unsensitised emulsion explosive, and the method includes sensitising the emulsion explosive downstream of a downstream end of the vertically extending pipe.
