Coal Ratio an overview ScienceDirect Topics

With increasing overburden to coal ratio, the cost of removal of overburden (known as stripping cost) adds considerably to the cost of mining the coal beyond economic limit. To develop a mine, the break even stripping ratio (at the surface of the final pit) must be established. It is found from the formula:
