Jawaharlal Nehru Technological University Hyderabad B.Tech II DEVELOPMENT OF MINERAL DEPOSITS Previous Question Paper (March - 2022 - R18)

The role of a mining engineer is multifaceted, encompassing the entire lifecycle of a mineral deposit from exploration to mine closure. Their primary responsibilities include:

• Planning and Design: Designing mine layouts, selecting appropriate mining methods (surface or underground), and planning the sequence of extraction to optimize recovery and safety.
• Production Management: Overseeing daily operations, managing equipment deployment, and ensuring production targets are met while maintaining cost efficiency.
• Safety and Risk Management: Implementing rigorous safety protocols, managing ventilation, ground control, and emergency response systems to protect personnel and assets.
• Economic Evaluation: Conducting feasibility studies, cost-benefit analyses, and resource estimation to ensure the project's financial viability.
• Environmental Stewardship: Managing waste rock and tailings, controlling dust and noise, and executing land reclamation plans to minimize ecological impact.
• Technological Innovation: Integrating automation, digitalization, and advanced blasting techniques to improve productivity and reduce manual labor in hazardous zones.

Statutory bodies act as regulatory authorities that ensure mining operations comply with legal, safety, and environmental standards. Their key roles include:

• Directorate General of Mines Safety (DGMS): Acts as the primary regulatory body for mine safety in India. It enforces the Mines Act, 1952, conducts inspections, investigates accidents, and grants certificates of competency to mining personnel.
• Indian Bureau of Mines (IBM): Responsible for the conservation and systematic development of mineral resources. It approves mining plans and schemes, monitors environmental compliance, and maintains national mineral inventory data.
• Ministry of Mines and State Departments: These bodies oversee the allocation of mining leases, grant prospecting licenses, and ensure the collection of royalties and taxes to the government.
• State Pollution Control Boards (SPCB) and MoEFCC: These bodies regulate environmental clearances. They monitor air and water quality standards, ensure compliance with the Environment (Protection) Act, and oversee the management of hazardous waste.
• District Mineral Foundation (DMF): A statutory body that manages funds collected from mining companies to support local communities and infrastructure development in mining-affected areas.
