Coal Ratio - an overview | ScienceDirect Topics

In this case, the principal factor to be considered before adoption of open cast mining is the overburden to coal ratio, the physical characteristics of the seam, topography, and continuity of operation. With increasing overburden to coal ratio, the cost of removal of overburden (known as stripping cost) adds considerably to the cost of mining

Jan 09, 2016 Jan 09, 2016 vii) Stripping Ratio The ratio is most commonly expressed as: Strip Ratio (SR) is the mass of waste to be mined to obtain one unit mass of ore. Waste (tons) SR = ----- Ore (tons) For example, a 3:1 stripping ratio means that mining one cubic meter of ore will require mining three cubic meters of waste rock
