Blasting mats are used when explosives are detonated in places such as quarries or construction sites. The mats are placed over the blasting area to contain the blast, suppress noise [1] and dust as well as prevent high velocity rock fragments called fly rock (or flyrock) from damaging structures, [2] people or the environment in proximity to the blast site.

Rock blasting in Finland. 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.
Access mats are a category of matting that are generally used to provide temporary roads and worksites. Access mats are often used to access work sites in remote or environmentally sensitive areas, [5] such as bogs, wetlands or fens. For that reason, they are often referred to as swamp, bog or wetland mats.
Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay), and stabilizers. [1] It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, Northern Germany, and was patented in 1867.
Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .
AfE-Turm building demolition slow motion video Implosion of the Athlone Power Station cooling towers Blasting of a highway bridge in Aachen, Germany. In the controlled demolition industry, building implosion is the strategic placing of explosive material and timing of its detonation so that a structure collapses on itself in a matter of seconds, minimizing the physical damage to its immediate ...
Silicate and aluminate impurities from the ore and coke are combined in the blast furnace with a flux which lowers the viscosity of the slag. In the case of pig iron production, the flux consists mostly of a mixture of limestone and forsterite or in some cases dolomite. In the blast furnace the slag floats on top of the iron and is decanted for ...
Soda blasting can be used for cleaning timber, wood, oak beams, oak floors, doors, stairs & banisters, cars, boat hulls, masonry, and food processing equipment. Soda blasting can also be used to remove graffiti [2] and to clean structural steel. Soda blasting is very effective for mold and fire/smoke damage cleanup as it cleans and deodorizes.
