How to Calculate Cut and Fill for Earthworks Projects

Sep 06, 2017· The cut or fill depth for each cell is found by subtracting the average existing level of the cell from the average proposed level. If the resultant depth is positive then this is a fill cell, while a negative value indicates a cut cell. In either case, the volume is calculated by multiplying the cut or fill depth by the area of the grid cell.

Stoping

In shrinkage stoping, mining proceeds from the bottom upwards, in horizontal slices similar to cut and fill mining, with the broken ore being left in place for miners to work from. Because blasted rock takes up a greater volume than in situ rock due to swell factor , some of the blasted ore approximately 40 must be removed to provide
