Under cutting of any face or side or cause permit such under cutting to cause any over hanging . . . . . . . .
Discuss
Answer & Solution
Answer: Option B
Solution:
The correct answer is option B. Not permitted.

In coal mining regulations in India, under cutting of any face or side that may cause overhanging is not permitted. Under cutting refers to the removal of material from the bottom or lower portion of a coal seam, which can weaken the stability of the remaining coal and surrounding strata. Overhanging occurs when the upper layers of coal or rock are not adequately supported, posing a risk of collapse or falling material.

To ensure safety and prevent accidents in coal mines, it is crucial to avoid under cutting that can lead to overhanging. Therefore, the correct answer is option B. Not permitted, as per the regulations in India.
