In underground mining, which method involves vertical transport?

• A. Drift
• B. Open pit
• C. Shaft
• D. Bulk sample

Answer: (C)

Vertical transport in underground mining is provided by a shaft, a vertical or near-vertical opening that connects surface to the underground workings. A shaft carries ore, waste, equipment, and people, using a hoist or winder to move materials up and down and to supply ventilation down into the workings. This makes it the primary method for moving between surface and depth when true vertical access is needed. In contrast, a drift is a horizontal tunnel used to access or develop the ore body, open pit refers to mining on the surface, and bulk sample is simply a small-scale sample extraction, not a transport method.
