Jawaharlal Nehru Technological University Hyderabad B.Tech IV PLANNING OF UNDERGROUND COAL MINING PROJECT Previous Question Paper (February/March - 2022 - R16)

A Feasibility Report is a comprehensive technical and economic document prepared to determine the viability of a mining project. It is based on detailed exploration data, including geological modeling, reserve estimation, and geotechnical studies. The report evaluates the selection of mining methods, infrastructure requirements, equipment procurement, and environmental impact assessments. It provides a detailed financial analysis, including Capital Expenditure (CAPEX), Operational Expenditure (OPEX), Internal Rate of Return (IRR), and Net Present Value (NPV), serving as the primary document for investment approval and project sanctioning.

A Pre-feasibility Report is an intermediate study conducted to assess whether a project warrants a full feasibility study. It provides a preliminary evaluation of the technical and economic aspects based on available data, often with a lower level of confidence than a final feasibility report. Its primary purpose is to identify critical constraints, potential fatal flaws, and the range of economic viability, thereby helping management decide whether to proceed with further exploration or more detailed engineering designs.
