    So, the ratio of overburden: coal is 3300:150, or 22:1. This stripping ratio is higher than the 20:1 limit, so surface mining of the coal seam to this depth would not be economic. Clearly, at greater depths, proportionately more overburden has to be removed per volume of coal, and this steadily increases the stripping ratio.
