Tin mining in Britain

http://dbpedia.org/resource/Tin_mining_in_Britain

Tin mining in Britain took place from prehistoric times, during Bronze Age Britain, until the 20th century. Mention of tin mining in Britain was made by many Classical writers. Tin is necessary to smelt bronze, an alloy that played a vital cultural role during the Bronze Age. As South-West Britain was one of the few parts of Anglian stage England to escape glaciation, tin ore was readily available on the surface. Originally it is likely that cassiterite alluvial deposits in the gravels of streams were exploited but later underground working took place. Shallow cuttings were then used to extract ore. In the 19th century advances in mining engineering enabled the exploitation of much deeper mines. In a few cases these mines even extended both to multiple levels and workings below the seabed. rdf:langString
从史前时期的青铜时代,不列颠群岛就有锡矿开采,一直进行到20世纪。在青铜时代,锡在制作青铜合金过程中有着非常重要的作用。由于英国西南部康沃尔郡和德文郡是在更新世的盎格鲁阶段里,英国为数不多的逃过冰期的地区之一,所以在地表中就能找到锡矿。起初可能是在河流砾石冲击层里开采锡石,这是炼锡的主要原料。然后在地下浅层里开采,需要通过浅浅的切削来采矿。19世纪开始采用先进的深层采矿,这些锡矿甚至延伸到海床下好几个地层。 rdf:langString
