Figure 4 is a 3D view of the four phasepits of the optimized phase plan, where phase4 pit is also the best ultimate pit. Figure 5 is a vertical cross section of the phasepits superimposed on the coal seams in the column model. The direction of phase expansion can be clearly seen from these figures. One can also see the rationality of the optimization results from the spatial relationship ...
