Deep Mining |
|||
|
Although mining undertaken in shallow mines just below the surface continued, the late eighteenth and early nineteenth centuries saw mines reach new and increased depths. In 1700 the deepest mines were about 165 feet (50 metres). By the 1830s the deepest mining shafts in Staffordshire reached 1,960 feet (600 metres).
