any of the two methods of mining i.e., surface mining methods and underground mining methods. Surface mining operations can be classified into open pit, opencast, strip, alluvial and in-situ mining, depending on method of mining being considered (Hartman, 1987). Open-pit mining is a method of developing and exploiting the deposit by making …
