In rat-hole mining, which of the following minerals is mined?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Coal.
Rat-hole mining is a primitive and hazardous method of coal extraction, primarily practiced in the northeastern state of Meghalaya, India. In this technique, narrow tunnels—just large enough for one person to crawl through—are dug into the ground to reach coal seams. Miners extract coal manually, often without proper safety measures or ventilation. This method is especially used in areas where conventional mining is difficult due to terrain or legal restrictions. Despite its dangers and environmental impact, rat-hole mining persists due to economic dependence and lack of alternatives for local communities.
Other options :
- Gold: Mined using deep-shaft or open-pit methods; not associated with rat-hole mining.
- Nickel: Typically extracted through large-scale industrial mining; not feasible via rat-hole techniques.
- Bauxite: Surface mining is used for bauxite; rat-hole mining is unsuitable for this mineral.
