This command calculates strata quantities based on coal sections and polylines along each cut. The coal sections contain the thickness for each strata and the entry width. When defining the coal section format in Coal Section Info, the Entry Width option must be activated.
Before running Quantities by Centerlines, polylines should be drawn along each cut. This routine sums the polyline lengths to find the linear feet of advance. Crossing cut polylines are handled by subtracting one entry width from the length for each crossing. Multiplying the linear feet of advance by the average entry width gives the mined area which is multiplied by the average strata thicknesses to obtain the strata volumes.
