Question

During development of metalliferous deposits, the method of connecting two levels from upper level to lower level is known as

• A. Winze
• B. Raise
• C. Cross cut
• D. Cross measure drift

Hint:

A simple way to remember:
- You Raise your hands up. A raise is driven upwards.
- You might Wince if you look down a deep hole. A winze is driven downwards.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question asks for the mining term for a vertical or inclined connection between two levels that is excavated in a downward direction.

Step 2: Detailed Explanation:
In underground mining, connections between different horizontal levels are essential for ventilation, transport of ore, and access for workers.
The terminology depends on the direction of excavation:
-

Raise: A vertical or inclined opening driven

upwards from a lower level to connect to an upper level.
-

Winze: A vertical or inclined opening driven

downwards from an upper level to connect to a lower level.
The question explicitly states the connection is made "from upper level to lower level," which means it is being driven downwards.
Therefore, the correct term is a winze.
Cross cuts and cross measure drifts are horizontal openings.

Step 3: Final Answer:
The connection driven from an upper level to a lower level is known as a winze.
This corresponds to option (A).
