2018-12-1 · ANFO is an explosive mixture of Ammonium Nitrate (AN) and Fuel Oil (FO). These two constituents act as oxidiser and fuel respectively, in the reaction that takes place during detonation. The normal fuel oil used is diesoline, and the trade name for ANFO made at AECI Mining Explosives is ‘ANFEX®’. Owing to its safety, low cost and ease-of-use ANFO is still
2015-8-7 · ANFO ANFO was first introduced into South African underground tabular mining operations in 1963, and by 1975 accounted for approximately 60% of the commercial explosives consumption within the sector. Not only did ANFO increase the level of safety of commercial explosives, but it was less expensive than dynamites, ‘less arduous’ to handle
ANFO Description ANFO is a free flowing (loose poured) mixture of porous (FO), formulated to be oxygen balanced for use in dry blastholes. ANFO is suitable for most dry blasting applications. It is not applicable in ground containing reactive sulphides. ANFO is Orica Mining Services 1 Nicholson Street Melbourne, VIC 3000
2021-12-1 · iRing Inc has introduced what it says is an extensive, searchable, comprehensive Knowledge Base that provides answers to questions concerning the use of commercial explosives in mining and construction applications including the physics of the detonation reaction and how this is used in mining for fragmentation.
ANFO Explosive A Versatile Solution. Ammonium Nitrate is an adaptable oxidizer that works well when explosions are needed during mining or quarrying operations. When combined with fuel oil, it makes an effective explosive that has a wide

Traditional bulk explosive products for surface mining applications (ANFO, heavy ANFO and pumped emulsion-based explosives) span a range of relative bulk strengths (RBS) from approximately 100 to 200 percent of that of ANFO. In this paper, RBS has been derived from the effective energy of detonation for each product in question, which
Application Recommendations • Low density AMMONIUM NITRATE is used extensively in the mining industry and is intentionally made very porous to allow for the rapid uptake of liquid fuel oil. The prill is coated with a paraffin which makes the AMMONIUM NITRATE difficult to dissolve and use for other applications.
anfo application to mining silhouetteyachts.co.za. ANFO has found wide use in coal mining, quarrying, metal mining, and civil construction in applications where its low cost and ease of use may outweigh the benefits of other explosives, such as water resistance, oxygen balance, higher detonation velocity, or performance in small-diameter columns.
