The use of ANFO originated in the 1950s. [3] It has found wide use in coal mining, quarrying, metal ore 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
Drilling and blasting is the controlled use of explosives and other methods, such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is often known as a rock cut.
Its other major use is as a component of explosive mixtures used in mining, quarrying, and civil construction. It is the major constituent of ANFO, a popular industrial explosive which accounts for 80% of explosives used in North America; similar formulations have been used in improvised explosive devices.
Extrudable explosives are an extremely viscous liquid, similar in properties to silicone based caulking materials used in construction. It is used in similar ways - stored in a container, then extruded out a nozzle into thin cracks, holes, or along surfaces. Some extrudable explosives can then be hardened using a heat curing process.
This is a typical "default" rating for connecting charges for blasting; lighter detonating cords may be used for "low noise blasting" and movie special effects, while heavier cords, used where the cord is employed to have some direct explosive effect—such as for precision rock carving work—may use 50 to 250 grain/foot (10 to 50 g/m ...
(Reuters) -Major food companies, including Kraft Heinz, Mondelez and Coca-Cola, were hit with a new lawsuit in the U.S. on Tuesday accusing them of designing and marketing "ultra-processed" foods ...
1988 Kansas City explosion: On 29 November 1988, at 4:07 AM two trailers containing approximately 23,000 kg (50,000 lb) of the explosive ANFO (ammonium nitrate with fuel oil) exploded at a construction site located near the 87th street exit of Highway 71 in Kansas City, Missouri. The explosives were to be used in the blasting of rock while ...
