SURFACE RUNOFF IN MINE A Mine A is a large opencast mine of MCL with a production capacity of 20 million tonnes per year. The mining lease falls in the Angul-Talcher region, which was identified as one of the critically polluted areas. The main drainage of the mine is Brahmani River which flows at a distance of about 10 Km from the lease boundary.
3. Mining Methods • Coal is mined by two main methods - surface or 'opencast' mining and 'underground' mining. • The choice of method is largely determined by the depth, geology of the coal deposit and other factors. • The majority of the world's coal production is coming from Opencast mines.

OPENCAST (STRIP) MINING Introduction: Opencast (strip) mining is a surface exploitation method, used mainly for coal and other bedded deposits, which resembles open pit mining. However, it differs in one unique respect: the overburden is not transported to waste dumps for disposal but cast directly into adjacent mined-out panels.
Strip (open cast) mining is used extensively for the surface mining of important commodities such as coal and phosphate ores. Casting is the process of excavation and dumping into a final location. This type of mining …
