The TMRP-6 (Serbo-Croatian, Croatian, Bosnian : Protivtenkovska Mina Razorno Probojna -6, Cyrillic script : Противтенковска Мина Разорно Пробојна -6) is a former Yugoslavian anti tank EFP mine.
Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within the ore, into soluble salts while the impurity remains insoluble.
The mine consists of a cast iron body in a thin steel sleeve. A central fuze well on the top of the mine is normally fitted with a pronged M605 pressure/tension (tripwire) fuze.
Note that detonation of an MS-3 under an anti-tank mine may cause sympathetic detonation of the larger munition. Additionally, an MS-3 could simply be used as a conventional boobytrap device without being buried, for example deliberately planted inside a building or a vehicle with some form of weight on top such as a suitcase.
Containing little more than 5.5 kilograms of TNT and a fuze activation pressure of approximately 200 lb (91 kg), the Teller mine was capable of blasting the tracks off any World War II-era tank or destroying a lightly armored vehicle. Due to its rather high operating pressure, only a vehicle or heavy object passing over the Teller mine would ...
Accordingly, the innovation of coal-fired steam power to work pumps was more versatile and effective to the mining industry than primitive means. The mine Wheal Vor had one of the earliest Newcomen engines (in-cylinder condensing engines, utilising sub-atmospheric pressure) before 1714, but Cornwall has no coalfield and coal imported from south ...
This is the raw material for the CPP, and consists of coal, rocks, middlings, minerals and contamination. Contamination is usually introduced by the mining process and may include machine parts, used consumables and parts of ground engaging tools. ROM coal can have a large variability of moisture and maximum particle size.
Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits. The metal or gemstones, having been moved by stream flow from an original source such as a vein, are ...
