Contraband
Contraband (from Medieval French ''contrebande'' "smuggling") refers to any item that, relating to its nature, is illegal to be possessed or sold. It is used for goods that by their nature are considered too dangerous or offensive in the eyes of the legislator—termed contraband ''in se''—and forbidden. So-called derivative contraband refers to goods that may normally be owned, but are liable to be seized because they were used in committing an unlawful act and hence begot illegally, e.g. smuggling goods; stolen goods – knowingly participating in their trade is an offense in itself, called fencing.

Coal Mine
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a ' pit head'. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavil ...

Firedamp
Firedamp is any flammable gas found in coal mines, typically coalbed methane. It is particularly found in areas where the coal is bituminous. The gas accumulates in pockets in the coal and adjacent strata and when they are penetrated the release can trigger explosions. Historically, if such a pocket was highly pressurized, it was termed a "bag of foulness". Name Damp is the collective name given to all gases (other than air) found in coal mines in Great Britain and North America. As well as firedamp, other damps include '' blackdamp'' (nonbreathable mixture of carbon dioxide, water vapour and other gases); whitedamp (carbon monoxide and other gases produced by combustion); poisonous, explosive '' stinkdamp'' (hydrogen sulfide), with its characteristic rotten-egg odour; and the insidiously lethal '' afterdamp'' (carbon monoxide and other gases) which are produced following explosions of firedamp or coal dust.
