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. [3]
They come in A0, A1, and M1300 configurations. The M1070 is coupled to a DRS Technologies M1000 semi-trailer. The M1300 is a U.S. Army Europe-specific derivative designed to be road legal within Europe and operates with a different trailer. [7] They replaced the earlier Oshkosh M911 tractor unit and M747 semi-trailer.
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.
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.
A mistake during a Nov. 2 underground blast at an EWEB construction site in South Hills propelled rocks from the site into the side of a neighboring home.
Secondly, the blast "leaked" between the balls, reducing their velocity. [1] A second problem was the curvature of the mine. This was determined experimentally by Bledsoe, through a large number of test firings. After Bledsoe left the project to work at the Rheem corporation, William Kincheloe, another engineer, came onto the Claymore project. [1]
M6/A1/A2/A3/A4 Mk II (HE-Blast), Mk III Series, M15, M34 A mouse trap type detonating fuze; the A1–A3 are improvements in the fuze function, the A4 features a safety clip. M204/A1/A2 Mk II series, M26/A1, M61 A mouse trap type detonating fuze, 4–5 second delay, detonation sets off filler M206/A1/A2 Mk IIIA3, M15, M34
A Chinese metal-cased Type 59 anti-tank blast mine. Its design is typical of many post World War II anti-tank blast mines, circular with a central fuze well (fitted with a plug in this case). An Italian, plastic cased blast resistant VS-2.2 mine. Capable of being deployed from the air, as well as being resistant to explosive clearance techniques.
