Part A is compulsory. Answer all questions in Part A. Part B consists of 5 Units. Answer any one full question from each unit.
PART - A
What are the geological factors which control the mine design?
Answer
The primary geological factors controlling mine design include the ore body geometry (shape, thickness, dip, and depth), structural features (faults, folds, joints, and shear zones), geotechnical properties of the ore and host rock (compressive strength, RQD, and rock mass rating), and hydrogeological conditions (groundwater table and aquifer characteristics).
What are the different stages of mining planning cycle?
Answer
The mining planning cycle consists of the following stages:
- Exploration and resource estimation.
- Feasibility study and economic evaluation.
- Mine design and selection of mining method.
- Mine development and scheduling.
- Operational production and monitoring.
- Closure and reclamation.
