  • Determining Stripping Ratio Basic Mining Techniques

    Breakeven Stripping Ration The maximum allowable Stripping Ratio (SR max) defines break even stripping ratio (BESR) This represents the highest possible units of waste that can be handled If the SR exceeds the BESR then the operation will be uneconomical as the income generated by the ore is insufficient to offset the costs incurred in miningThe breakeven stripping ratio is a function of ore value and the costs involved Read More In coal mining: Contour strip mining If the breakeven stripping ratio remains favourable, further cuts into the hillside will be made Otherwise, if there are sufficient reserves under the knob of the hill, the coal may be recovered by underground miningBreakeven stripping ratio | Britannica
