the full width and height of the ore but leaving pillars for support of the back. The level plan thus becomes the ore outline. If the shaft is sunk outside the ore body, a short connecting crosscut from the shaft, and perhaps others to separate ore bodies, constitute all the development work required, the ore being mined as the workings advance.
