We divide the overburden thickness by ore thickness to get the stripping ratio For example if we have an overburden thickness of … WebThe break-even stripping ratio is a function of ore value and the costs involved. If the break-even 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 mining or by augering.

Web“sulfur decreased both ratios”. Based on the visual observations of stripping, it was concluded that the lower ratios were related to a loss of cohesion rather than a loss of adhesion. The SEA binders were weakened by the conditioning processes. Sulfur decreased both the dry and wet tensile strengths but did not lead to visual stripping.

Therefore, the stripping strength of an assembly depends on the shear strength of the nut and bolt materials. To determine the force required to strip the threads, multiply the shear strength by the cross sectional area being sheared. The difficulty lies in determining the
