Question

Which of the following is NOT typically a major component of long-term mine planning?

• A. Production scheduling and sequencing
• B. Pit optimization and ultimate pit limit determination
• C. Daily shift-wise blasting and pattern design
• D. Orebody modeling and reserve estimation

Hint:

Long-term planning focuses on \[ \boxed{ \text{Strategic mine design and production planning, not daily operations.} } \]

Answer 1

The Correct Option is C

Step 1: Recall the objectives of long-term mine planning. Long-term mine planning deals with strategic decisions such as: \[ \begin{aligned} &\bullet\ \text{Orebody modeling and reserve estimation,} &\bullet\ \text{Pit optimization,} &\bullet\ \text{Production scheduling and sequencing.} \end{aligned} \]

Step 2: Identify the activity that is not long-term. Daily shift-wise blasting and blast pattern design are operational (short-term) planning activities. Hence, \[ \boxed{\text{Daily shift-wise blasting and pattern design}} \] is the correct answer. Therefore, \[ \boxed{(C)} \] is the correct answer.
