Question

The method of stoping used for the extraction of Narrow vein deposits

• A. Sub level caving
• B. Resuing
• C. Room and Pillar method
• D. Cut and fill method

Hint:

The name "Resuing" is unique and specifically associated with narrow vein mining.
If you see it as an option for a question about narrow veins, it is very likely the correct answer.
It's the ultimate method for minimizing dilution when the ore is only a few inches or centimeters wide.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
We need to identify a mining method that is specifically suited for extracting narrow vein deposits.

Step 2: Detailed Explanation:
Narrow vein deposits pose a challenge because it's difficult to mine only the valuable ore without also mining the worthless wall rock, a problem called dilution.
-

Sub level caving and

Room and Pillar are generally used for much wider, more massive or tabular orebodies.
-

Cut and fill method is very common for vein deposits of various widths and is known for being selective, but there is an even more specialized method for very narrow veins.
-

Resuing Stoping: This is a highly selective mining method developed specifically for

very narrow, often high-grade, veins.
The process involves two separate steps in each cycle:
1. First, a slice of the waste wall rock adjacent to the vein is blasted and removed (or used as fill).
2. Second, the now-exposed narrow vein of clean ore is blasted and collected separately.
This two-stage process minimizes dilution, which is critical when the vein is very narrow and valuable.

Step 3: Final Answer:
Resuing is a specialized method used for the extraction of narrow vein deposits.
This corresponds to option (B).
