    The open-pit or open cast mining method is the obvious choice for a property with wide area of mineralization exposed or exists close to the surface and continues to greater depth. The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks.OPEN CAST MINE PLANNING Mining and Blasting,Opencast mines using draglines for over burden removal involve the excavation of a series of parallel strips and each strip or cut is worked in a series of blocks.
