PART - A
State at least four technical factors to be considered in mine planning.
Answer
Four technical factors for mine planning are: 1) Geological characteristics of the deposit, 2) Geotechnical properties of the host rock and ore, 3) Mining method selection, and 4) Equipment selection and capacity requirements.
Explain briefly the inputs required for short range mine planning.
Answer
Short-range mine planning requires inputs such as detailed geological data (grade control models), current face positions, equipment availability and performance metrics, operational constraints (e.g., safety, ventilation), and production targets for the specific period (daily, weekly, or monthly).
