The most visible feature of a mine shaft is the headframe (or winding tower, poppet head or pit head) which stands above the shaft. Depending on the type of hoist used, the top of the headframe will either house a hoist motor or a sheave wheel (with the hoist motor mounted on the ground).
A vertical mine shaft can be built quickly and allows safe, fast access to the deepest regions of the map. To descend to the bottom, simply walk into the shaft. You will pass over the ascent shaft, fall into the descent shaft, and land in the water pit. To ascend, climb the ladder and hop out.
The existing No. 10 Shaft at Resolution Mine is the deepest in the United States and the No. 9 Shaft will be at the same depth at completion. Connecting the shafts will provide a second means of egress between the two shafts as well as improve ventilation.
I could upgrade a mine shaft that will give me 3.5aa/s more, and about 3.5aa/s overall when done, OR I could upgrade another mine and get 2.3aa/s more, but 9.7aa/s overall. The first one gets more money produced, but if I use super managers, it could be better to upgrade the higher producing mine because I can use only one mine shaft with a SM.
