Abstract
An explosive composition is provided that is comprised of a Heavy ANFO and grain hulls. In one embodiment, the grain hulls are comprised of rice hulls. The grain hulls serve both as an inert bulking additive that reduces the density of the composition and as a sensitizer that reduces the energy needed to reliably detonate the composition. Also provided is a method for manufacturing an explosive composition comprised of Heavy ANFO and grain hulls, such as rice hulls. Additionally, a method of using an explosive comprised of ANFO and grain hulls in a mining operation is disclosed.

An explosive composition comprising:
- a Heavy ANFO comprising:
- an explosive emulsion;
- and
- an ammonium nitrate based explosive;
- and
- an inert bulking and sensitizing additive comprising rice hulls;
- wherein said inert bulking and sensitizing additive is substantially devoid of components of rice other than said rice hulls;
- wherein said Heavy ANFO and said inert bulking and sensitizing additive have a bulk density in a range of 0.35 gm/cc to 1.33 gm/cc.
(canceled)
An explosive composition comprising:
- a Heavy ANFO comprising:
- an explosive emulsion;
