  • Calculation example - Seam true thickness and gradient calculation

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.

Calculation example - Seam true thickness and gradient calculation

(a) True thickness

32 capture 1

(b) Gradient of seam

32 capture 2

Thus, Gradient is 1 in 1.072
