Question:
Insufficient stemming causes
Insufficient stemming causes
Show Hint
Proper stemming prevents gas escape and ensures effective blasting.
Updated On: May 28, 2025
- Over breakage of coal
- Excessive vibration
- Blown out shot
- High powder factor
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Stemming is the process of compacting inert material into a blast hole above the explosive charge. Insufficient stemming allows gases to escape, causing blown out shots.
