Cost of Stoping for Underground Mining

In figure 119, direct stoping costs are plotted against approximate vein or stoping widths, in feet, for a number of mines employing, respectively, open stoping, shrinkage stoping, and cut-and-fill stoping, and thus indicate the effect of width upon direct stoping cost per ton of ore. High costs in narrow stopes are due principally to reduction in tons broken per foot of hole drilled and hence
