Commonly used mining techniques to extract coal

2018-1-25  Contour strip mining and area strip mining are the two forms of strip mining, which is often used to extract coal and lignite. In contour strip mining, bulldozers or power shovels are deployed to take away huge amounts of ground material in terraced strips for extracting coal from a seam on a hill. Area strip mining is commonly used on flat terrain to extract deposits spread over a large area.

2016-5-1  The strip ratio (SR) is the simplest measure of mining efficiency. Strip ratio is the fraction of overburden (or waste ore) versus the weight of bitumen-rich oil sands. A strip ratio of 2 is considered high but feasible if the ore grade is high enough. A better measure of mining economics is the TV:BIP ratio. TV:BIP is defined as the total mining
