(a) True thickness
(b) Gradient of seam
Thus, Gradient is 1 in 1.072
Calculation example - Seam true thickness and gradient calculation Written by TheCivilEngineer.org
A vertical borehole passes through a seam with a known dip at 43o. If the apparent thickness of the seam as shown by the borehole core is 2m, calculate: (a) the true thickness of the seam and (b) the gradient of the seam.
