The coal seam covers 150 mm 2 squares, whereas the overburden covers 33 cm 2 squares, i.e. 33 × 100= 3300 mm 2 squares. 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. ... They start with the removal of topsoil by ...
