CUT-OFF STRIPPING RATIO
It is the ratio of thickness of Coal to OB ratio.
Cut-Off Stripping Ratio सिर्फ एक particular point के लिए रहेगा ।
*Example*
Calculate Cut-Off Stripping Ratio, if Coal seam thickness 10m and cover of OB is 35m.
Cut-Off Stripping Ratio = Thickness of Coal Seam / Thickness of OB
= 10 / 35
Cut-Off Stripping Ratio = 1:3.5
1 - Coal in Tonne , 3.5 - OB in Cubic Meter
