Abstract:
A method of preparing heavy ANFO including loading high density ammonium nitrate into a hopper; feeding the high density ammonium nitrate into a mixing chamber; during the feeding step, injecting fuel into a high density ammonium nitrate feeding pipe, thereby obtaining ANFO; loading bulk emulsion into a hopper; gassing the bulk emulsion; feeding the gassed bulk emulsion into a same mixing chamber as the ANFO; and mixing the gassed bulk emulsion and the ANFO, thereby obtaining heavy ANFO.
