Surface mining Methods or Techniques When mining of a mineral deposit including stones of various kinds is undertaken by exposing them to the atmosphere ( open air and sun), it is known as surface mining. Based on the location of the deposit, the surface datum, the mines can be classified as open pit, opencast, quarrying or underground.
