the analytical formulas of discernment error are derived
and the discernment error for trapezoid cross-section of coal heap with different height are calculated. According to the residue of formulas for double trapezoid integral and central limit theorem
the distribution function which are in accord with Gauss for discernment errors of total volumes are derived. Finally
some conclusions about error estimating for a series of cases are presented
