Abstract
An apparatus and method for converting uninhibited bulk explosives or oxidiser into inhibited bulk explosives or oxidiser on demand. The apparatus disperses an inhibitor into a stream of bulk explosive/oxidiser during the conveyance between an explosive truck and a blast hole or in preparation of a bulk oxidiser for use in a bulk explosive vehicle.
Claims19
An apparatus for selectively outputting either one at a time of two alternative outputs, the alternative outputs consisting of:
- an uninhibited bulk explosive or oxidiser and an inhibited bulk explosive or oxidiser comprising:
- an outlet for streaming an output of bulk explosive;
- and
- one or more dispersion means for adding, or not adding, an inhibitor on demand into a stream of uninhibited bulk explosive exiting the outlet so as to convert uninhibited bulk explosive into inhibited bulk explosive when the inhibitor is added during output of the bulk.
An apparatus for selectively outputting either one at a time of two alternative outputs, the alternative outputs consisting of:
- an uninhibited bulk explosive oxidiser and an inhibited bulk explosive oxidiser, the apparatus comprising:
- an outlet for streaming an output of bulk explosive oxidiser;
- and
- a dispersion means for adding, or not adding an inhibitor on demand into a stream of uninhibited bulk explosive oxidiser exiting the outlet so as to convert uninhibited bulk explosive oxidiser into inhibited bulk explosive oxidiser when the inhibitor is added during output of the bulk explosive oxidiser.
An apparatus according to claim 12, wherein the inhibitor added is or substantially is dry.
A vehicle for producing an inhibited bulk explosive at the site of use of the inhibited bulk explosive, the vehicle comprising:
- a storage for carrying inhibited bulk explosive oxidizer and a storage for the least one other ingredient to the site of a blast hole and a dispersion means for adding the least one other ingredient into a stream of inhibited bulk explosive oxidiser from the storage so as to convert the stream of inhibited bulk explosive oxidiser into a stream of inhibited bulk explosive for insertion into a blast hole.
A device for selectively outputting either one at a time of two alternative outputs, the alternative outputs consisting of:
- an uninhibited bulk explosive and an inhibited bulk explosive, the device comprising:
- a conduit for streaming of a bulk explosive from a receptacle into a blast hole;
- the conduit in operative association with means for selectively adding, or not adding, an inhibitor on demand to the stream such that when added the uninhibited bulk explosive is converted to an inhibited bulk explosive.
A method for selectively outputting either one at a time of two alternative outputs, the alternative outputs consisting of:
- an uninhibited bulk explosive and an inhibited bulk explosive for insertion into a blast hole comprising:
- streaming uninhibited bulk explosive from an outlet;
- and
- adding, or not adding, an inhibitor on demand into the stream of uninhibited bulk explosive at the blast hole such that when added the uninhibited bulk explosive is converted to an inhibited bulk explosive.
A method for outputting an inhibited bulk explosive comprising:
- conveying inhibited bulk explosive oxidiser and fuel oil to the site of a blast hole;
- streaming inhibited bulk oxidiser from an outlet;
- and
- adding fuel oil into the stream of inhibited explosive oxidiser so as to produce a stream of inhibited bulk explosive into the blast hole.
