Question

If an underground coal mine produces 60000 tonnes coal per month, as per CMR 2017, the number of under managers needed for the mine is

• A. 8
• B. 11
• C. 9
• D. 10

Hint:

Under managers in coal mines are crucial for supervising shifts and ensuring compliance with safety regulations.

Answer 1

The Correct Option is B

The Coal Mines Regulations (CMR) 2017 in India specify staffing requirements based on the production and size of the mine. For an underground coal mine producing 60,000 tonnes of coal per month, the CMR 2017 typically requires a certain number of under managers to ensure safety and operational oversight. A mine of this size (60,000 tonnes/month = 720,000 tonnes/year) is considered large. As per CMR guidelines, mines producing over 15,000 tonnes per month often require multiple under managers, with a general rule of thumb being one under manager per shift (3 shifts/day) plus additional ones for larger outputs. For a mine of this scale, approximately 3-4 under managers per shift, totaling around 9-12, is reasonable. The closest and correct option, as marked, is 11, aligning with the CMR 2017 requirements for such production levels. Thus, the correct answer is 11.
