1. Introduction. Emulsion explosives (EE) are one of the most recently developed classes of energetic materials [1,2,3,4,5] and can be perceived as a step forward from the traditional energetic materials based on ammonium nitrate (AN), such as amatols, ammonals and ANFO (ammonium nitrate-fuel oil).EEs are obtained by physically or chemically …
On April 19, 1995, at 9:02 a.m. a forty-eight-hundred-pound ammonium nitrate–fuel oil bomb exploded in a Ryder truck parked at the north entrance of the Alfred P. Murrah Federal Building in downtown Oklahoma City, killing 168 people and injuring approximately 850. The governor's office reported that thirty children were orphaned, 219 children ...
ANFO is an extremely explosive compound and it is formed from the mixture of 94% prilled ammonium nitrate (AN) and 6% Fuel Oil (FO) (Cook, 1974), it's a widely used explosive and accounts for 80% of all blasts that occur in the United States (Green, 2006). The reason that ANFO is so widely used in industries such as mining, quarrying, and ...
Other articles where ANFO is discussed: explosive: Ammonium nitrate–fuel oil mixtures: In 1955 it was discovered that mixtures of ammonium nitrate and fine coal dust would give very satisfactory blasting results in the large (about 22.5-centimetre, 9-inch) holes used in open-pit coal mines to remove the rock and soil covering the coal.…
Manufacturing ammonium nitrate fuel oil (ANFO) explosives is a relatively simple process, which involves combining the correct proportions of explosively reactive substances. The components of ANFO are usually mixed close to the point of operation for safety reasons. The final product, once mixed, is relatively safe and easy to handle.
An ANFO mixture of 94 pct ammonium nitrate, 6 pct fuel oil is close to optimum from the perspective of minimum toxic fumes production. Previous research and theory show that the detonating ANFO will produce excessive levels of nitrogen oxides if the fuel oil content is too low and will produce excessive

Thermal decomposition can lead to release of irritating gases and vapors. Keep product and empty container away from heat and ... (solid,gas) No information available Explosion Limits No ...
The ammonium nitrate (AN) and fuel oil (FO) mixture known as ANFO is a typical representative of non-ideal explosives. In contrast to ideal explosives, the detonation behavior of ANFO exhibits a strong dependence on charge diameter, existence, and properties of confinement, with a large failure diameter and long distance required to establish steady-state …
On 4 August 2020, an estimated 2.75 kt of ammonium nitrate exploded in the Port of Beirut, Lebanon. Rigby et al. (Shock Waves 30:671–675, 2020) used observations from numerous video recordings of the explosion to estimate the time-of-arrival of the primary shock at 38 positions, the distances of which from the centre of the explosion were determined from …

Ammonium nitrate-fuel oil mixture is commercially available as pale white, gray, yellow, or pink oil-covered prills with a petroleum odor. Non-commercially produced forms may be darker in color. It is used for blasting rock and in some types of mining. It will accelerate the burning of combustible materials. The ammonium nitrate is soluble in ...
As ammonium nitrate has oxidizing properties, it can easily release oxygen into the air. This can make it highly explosive when combined with combustible substances. When mixed with fuels like fuel oil and aluminum powder or with explosives like TNT, ammonium nitrate easily creates explosive compounds, including Amatex, Amatol, Minol, Tovex, etc.
As synthetic ammonia became less expensive because of improvements in manufacture and a raw material change from coal to natural gas, the explosives industry concentrated its efforts on substituting ammonium nitrate for nitroglycerin. Two important products were (1) low-density ammonia dynamites and (2) semigelatins. Prior to their …
Ammonium nitrate/fuel oil (ANFO) explosive vehicle is the most common equipment in the mining machinery. The pharmaceutical system is the most important system of the whole mechanical system, its performance and reliability determine the reliability of the whole system. However, there is little literature on reliability analysis of ANFO explosive vehicle. In …
Ammonium nitrate, by itself, is not considered to be a donor when applying this table. ammonium nitrate (AN), ammonium nitrate-fuel oil (ANFO) or combinations thereof are acceptors. If stores of AN are located within the sympathetic detonation distance of explosives or blasting agents, one-half the mass of the AN is to be included in the mass of the donor.
Ammonium Nitrate Fuel Oil (ANFO) Any carbonaceous material mixed with ammonium nitrate (AN) will produce a possible explosive mixture. In fact AN, as a pure material is not classified as an explosive for transportation and storage unless it contains >0.4% carbonaceous material. However, there have been many apparent incidences of pure AN being ...
The modified powdery mixture of ammonium nitrate and fuel oil (MPANFO) is a new breed of industrial explosives developed years ago in China. As one of the important properties of an industrial explosive, the channel effect of MPANFO was reported in this paper. A series of experiments were conducted to determine the channel effect of MPANFO.
explosives such as Ammonium Nitrate and Fuel Oil (ANFO). In this study, the effect of reaction zone flow di-vergence on ANFO detonation was explored through variation of the inert confinement and explosive diameter in the rate-stick geometry with cylinder expansion experiments. New tests are discussed and compared to prior experiments.
