This invention relates to a method of producing a composition comprising solid particulate ammonium nitrate having improved explosive properties. n Explosive compositions comprising particulate ammonium nitrate such as ANFO, which is a mixture of particulate ammonium nitrate and about 6% w/w of a fuel oil which is typically distillate oil, have been known for many years as relatively inexpensive and reliable explosives. n Despite the wide acceptance of particulate ammonium nitrate based exposlives in the industry, their use has been limited by their relatively poor performance in wet conditions; in such conditions, explosive power can be seriously reduced, and they can be difficult to detonate. |
