Abstract
Systems for delivering explosives with variable densities are disclosed herein. Methods of delivering explosives with variable densities and methods of varying the energy of explosives in a blasthole are disclosed herein.
Claims21
1-27. (canceled)
A method for varying the explosive energy of explosives delivered to a blasthole, the method comprising:
- determining rock and/or ore properties along a length or depth of a blasthole;
- mixing a gassing agent with an explosive composition to form a sensitized explosive for flowing into the blasthole;
- and
- loading the blasthole with the sensitized explosive according to a blasthole explosive density profile, wherein the blasthole explosive density profile is based on the rock and/or ore properties along the length or depth of the blasthole.

A method for varying the explosive energy of explosives delivered to a blasthole, the method comprising:
- determining rock and/or ore properties along a length or depth of a blasthole;
- mixing a gassing agent with an emulsion matrix proximal an outlet of a delivery conduit to form a sensitized explosive for flowing into the blasthole;
- and
- loading the blasthole with the sensitized explosive according to a blasthole explosive density profile, wherein the blasthole explosive density profile is based on the rock and/or ore properties along the length or depth of the blasthole.

A method for varying the explosive energy of explosives delivered to a blasthole, the method comprising:
- determining rock and/or ore properties along a length or depth of a blasthole;
- mixing a gassing agent with an emulsion matrix to form a sensitized explosive for flowing into the blasthole;
- determining a blasthole explosive density profile based on the rock and/or ore properties along the length or depth of the blasthole, wherein the blasthole explosive density profile comprises desired densities in discrete segments of the blasthole;
- and
- loading the blasthole with the sensitized explosive according to the blasthole explosive density profile.
