The ideal mixture, i.e., the oxygen-balanced mixture, consists of 3 moles of ammonium nitrate and one mole of fuel oil. Next, we should find the weight ratio of ammonium nitrate to fuel oil. For 3 moles of NH 4 NO 3 3*80.05 240.15 g. For 1 mole of CH 2 1*14.03 14.03 g. The molecular weight of ANFO is, therefore 240.15 14.03 254.18 g.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.

ANFO trucks include many features dependent on each manufacturer, such as maximum boom reach that supports multiple heading applications. ANFO trucks are purpose-built and designed to meet the rugged environments of underground mining. ANFO charging trucks are made for high speed and high density charging in all directions. Dec 31, 2020 plied in the mining industry, has a 20% void fraction and is much more energy-efcient 4. However, AN-PP is highly soluble in water, which limits ANFO application in dry bore-holes in open-strip mining. Despite this fact, ANFO remains one of the most commonly May 01, 2021 Mining is the largest consumer of civil explosives including other rock blasting applications such as quarrying and tunnelling. Gunpowder also known as black powder was the first generation of explosives used in all applications. ... A view from history to the present use of ANFO.

An increase in blast-hole dia. beyond 300 mm decreases the sensitivity to initiation of ANFO explosives. With above 4 percent water an ANFO the velocity of detonation deceases sharply and the mixture with 9 percent or more water cannot be detonated. When using ANFO, it is essential to have uniform mixing of ammonium nitrate and fuel oil. When mining conditions pemzit, bulk ANFO, a mixture of ammonium nitrate and fuel oil, is the e.lplosive of choice. ANFO is less costly than other explosives but it dissolves readily in water. Several case histories in the United States and Canada show a clear connection between uncontrolled losses of bulk plosives and high ni overall mining operation. ANFO is a ...

Nov 11, 2013 Charging with ANFO generally requires Air Pressure. That means a Compressor topside. Youll need a Compressor anyway to run the hand-held drill. There are lots of small, portable pneumatic ANFO loaders available which would be suitable for your application. Just google ANFO Loader . Bear in mind ANFO needs to be Primed. ANFO is widely used as an explosive in mining, quarrying, and tunneling construction or wherever dry conditions exist. The following pie chart shows world consumption of explosives The largest consumers of explosives in industrial applications are China, the United States, the Commonwealth of Independent States, and Central and South America. Its main application is for blasting in mining and quarrying applications, where one requires a sizable chunk of rock / dirt / land to be fragmented for easy handling by your machines. Can you imagine a machine trying to chip away at an expanse of bedrock? Very time consuming and costly. Enter ANFO.

S Widodo. 1, H Anwar. 2. and N A Syafitri. 3. 1. Mining Engineering Department, Hasanuddin University, Dec 31, 1996 The Bureau of Mines conducted research to determine the safe operating conditions for using recycled (used) lubricating oil from mining equipment as a partial replacement for diesel fuel to make ANFO-type blasting agents. The use of recycled oil (RO) saves energy, reduces oil imports, and reduces mining costs. 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 ...
