Opencast Mining an overview ScienceDirect Topics,Coal is mined either by surface methods opencut or opencast mining or by underground techniques In surface mining all of the rock from the ground surface to the top of the seam material referred to as overburden is removed and set aside to expose the coal which is then taken out and transported from the mine for preparation and use Figure 11 ...

Known as opencast mining in areas outside of the united states the process involves digging out minerals or rocks by eliminating them from a borrow or open pit it is called open pit to distinguish it from mining methods that use extractions that include tunneling into the earth when minerals or rocks that are good for commercial purposes areFurther Details
InOpenpit Mining Opencast Mining Opencut Mining StripThe process of Coal mining has developed over the years and different methods have been evolved to extract the mineral which is available in different terrains across the world The most economical method of extracting coal depends upon the depth and the quality of the coal seamsFurther Details
Opencast and deep mining differences openpit mining opencut mining or opencast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow this form of mining differs from extractive methopencast and deep mining differencesFurther Details
