Read MoreGenerally, mining techniques can be broadly classified into two types, they are Surface Mining and Underground Mining. In pre-historic period, when the people had found metals like copper, iron on or close to earth surface, they used to manufacture some tools and weapons. The ancient known mine is the “Lion Cave” which is in Swaziland ...
