Explanation:

Employee energy awareness index is not a common energy performance indicator used in Mine Energy Management.

What is the importance of energy management in sustainable mining practices?

  1. To reduce the environmental impact of mining operations

  2. To improve the efficiency and profitability of mining operations

  3. To comply with environmental regulations

  4. All of the above


Correct Option: D
Explanation:

Energy management plays a crucial role in sustainable mining practices by reducing the environmental impact of mining operations, improving the efficiency and profitability of mining operations, and helping to comply with environmental regulations.

Which of the following is NOT a common energy conservation strategy in surface mining operations?

  1. Using energy-efficient haul trucks

  2. Optimizing blasting patterns

  3. Reducing overburden removal

  4. Using solar panels to power mining equipment


Correct Option: D
Explanation:

Using solar panels to power mining equipment is not a common energy conservation strategy in surface mining operations due to the intermittent nature of solar power and the high upfront costs associated with solar panel installation.

What is the role of energy storage systems in Mine Energy Management?
