Question:
Resuing method of mining is practiced for
Resuing method of mining is practiced for
Show Hint
Use resuing only where high selectivity is required, typically in very narrow ore veins.
Updated On: Dec 26, 2025
- thick vein deposit.
- massive shallow deposit.
- narrow vein deposit.
- massive deep-seated deposit.
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Resuing is a highly selective underground mining method used where ore and waste must be separated.
Step 1: In resuing, waste rock is blasted and removed first, then the ore is blasted separately to avoid dilution.
Step 2: This technique is necessary only when ore bodies are extremely narrow, and mixing waste with ore would drastically reduce grade.
Step 3: Thick or massive deposits do not require such selectivity.
Therefore, resuing is practiced for narrow vein deposits.
