Abstract

A method of providing an emulsion explosive underground in a mine (10) having a downwardly extending mine shaft (12) and a cage (14) arranged for travelling along the mine shaft (12) includes transferring an emulsion explosive fuel underground, transferring an emulsion explosive oxidiser underground along a downwardly extending conduit (28) located inside the mine shaft (12), and mixing the emulsion explosive fuel and the emulsion explosive oxidiser underground in the mine to provide an emulsion explosive.
