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
An explosives delivery system comprising:
- a first reservoir configured to store a first gassing agent, wherein the first gassing agent comprises a pH control agent;
- a second reservoir configured to store a second gassing agent, wherein the second gassing agent comprises a chemical gassing agent;
- a third reservoir configured to store an emulsion matrix;
- a homogenizer configured to mix the emulsion matrix and the first gassing agent into a homogenized product, the homogenizer operably connected to the first reservoir and the third reservoir;
- a delivery conduit operably connected to the homogenizer, wherein the delivery conduit is configured to convey the homogenized product, wherein the delivery conduit is configured for insertion into a blasthole, and wherein the second reservoir is operably connected to the delivery conduit proximal an outlet of the delivery conduit;
- and
- a mixer located proximal the outlet of the delivery conduit, wherein the mixer is configured to mix the homogenized product with at least the second gassing agent to form a sensitized explosive product.

An explosives delivery system comprising:
- a first reservoir configured to store a first gassing agent;
- a second reservoir configured to store a second gassing agent;
- a third reservoir configured to store an emulsion matrix;
- a homogenizer configured to mix the emulsion matrix and the first gassing agent into a homogenized product with increased viscosity and reduced oxidizer phase droplet size relative to the emulsion matrix, the homogenizer operably connected to the first reservoir and the third reservoir;
- a delivery conduit operably connected to the homogenizer, wherein the delivery conduit is configured to convey the homogenized product, wherein the delivery conduit is configured for insertion into a blasthole, and wherein the second reservoir is operably connected to the delivery conduit proximal an outlet of the delivery conduit;
- and
- a mixer located proximal the outlet of the delivery conduit, wherein the mixer is configured to mix the homogenized product with at least the second gassing agent to form a sensitized explosive product.

- a homogenizer configured to mix the emulsion matrix and the first gassing agent into a homogenized product, the homogenizer operably connected to the first reservoir and the third reservoir, the homogenizer configured to introduce a shearing stress on the emulsion matrix and the first gassing agent;
- a delivery conduit operably connected to the homogenizer, wherein the delivery conduit is configured to convey the homogenized product, wherein the delivery conduit is configured for insertion into a blasthole, and wherein the second reservoir is operably connected to the delivery conduit proximal an outlet of the delivery conduit;
- and
- a mixer located proximal the outlet of the delivery conduit, wherein the mixer is configured to mix the homogenized product with at least the second gassing agent to form a sensitized explosive product.
