A. Whether the shaft is or is not in use for operating the mine. b. The breaking character of the rock. c. The amount of water. The delays incident to general carrying of ore and men are such that the use of the main haulage engine for shaft-sinking is practically impossible, except on mines with small tonnage output. Even with a
