An apparatus and process for the manufacture of an emulsion explosive wherein the composition of emulsion explosive can be continually varied in a controlled manner. The apparatus comprises: (i) at least one mixing means suitable for blending components into an emulsion; (ii) at least one delivery means for delivering an emulsion explosive from said mixing means into a blasthole or package; (iii) at least one container for emulsion; (iv) at least two containers for components which on combination are suitable for forming a gas for the gassing emulsion; (v) optionally, further containers for optional components suitable for addition to the emulsion or emulsion explosive; (vi) supply means for the supply of said components from said containers to the mixing means; and (vii) control means for controlling the amount or rate of supply of components to the mixing means and thereby enabling the composition of the emulsion explosive to be continuously varied in a controlled manner.
Cette invention concerne un processus et un appareil qui permettent de fabriquer des explosifs de type émulsion, et de modifier continuellement et de manière commandée la composition de ces explosifs. Cet appareil comprend les éléments suivants: (i) un ou plusieurs systèmes de mélange permettant de mélanger des composants de manière à obtenir une émulsion; (ii) un ou plusieurs systèmes d'acheminement de l'explosif de type émulsion depuis le système de mélange dans un trou de mine ou emballage; (iii) un ou plusieurs contenants destinés à l'émulsion; (iv) deux contenants au moins destinés à des composants qui, lorsqu'ils sont combinés, forment un gaz servant au gazage de l'émulsion; (v) éventuellement d'autres contenants pour d'éventuels composants pouvant être ajoutés à l'émulsion ou à l'explosif de type émulsion; (vi) un système assurant l'alimentation desdits composants depuis les contenants vers le système de mélange; et enfin (vii), un système de commande de la quantité ou du débit d'alimentation en composants vers le système de mélange, lequel système de commande permet modifier continuellement et de manière contrôlée la composition de l'explosif de type émulsion.
