Study Notes
Importance of Mining
- Mining is essential for extracting valuable mineral deposits necessary for industry and technology.
- It supports the economies of many nations, making it crucial for economic survival.
- If a material cannot be grown, it must be sourced through mining.
Mining Methods
- Two primary mining methods exist: surface mining and underground mining.
Surface Mining
- Suitable for shallow deposits or when there is a low ore to waste ratio.
- Types of surface mining include:
- Open pit mining
- Open cast mining/strip mining
- Auger mining
- Quarrying, commonly practiced in Region 3.
Underground Mining
- Utilized when deposits are located deep underground, inaccessible by surface mining.
- Techniques in underground mining include:
- Block caving or sub-level caving
- Blasthole stoping
- Overhand cut and fill
- Shrinkage stoping
Stages of Mining Operation
- Exploration stage: Searching for mineral deposits.
- Development stage: Preparing the site for extraction.
- Production stage: Actual mining and extraction of minerals.
- Final mine rehabilitation and decommissioning: Restoring the site post-mining.
Environmental Impacts and Control Strategies
- Mining can significantly affect land and water resources, noise levels, and air quality.
- Strategies must be implemented to mitigate the environmental impact of mining activities.
Social Development Activities in Mining
- Programs support enterprise development and networking.
- Infrastructure development assistance improves mining-related services.
- Access to health services and facilities is prioritized for communities near mining operations.
Corporate Social Responsibility
- Mining companies are encouraged to assist in infrastructure development and support social programs.
Management and Employee Training
- Training for employees includes a variety of safety and emergency preparedness courses:
- Fire fighting training
- First aid and life support training
- Community-based first aid training
- Basic occupational safety and health training (BOSH)
Regulatory Framework
- Republic Act 7942 and DAO 2010-21 govern mining permits in the Philippines.
- Various permits can be issued by the DENR MGB and local governments, including:
- Quarry Permit: Valid for 5 years, renewable up to 25 years for a maximum area of 5 hectares.
- Sand and Gravel Permits: Limited to 5 hectares, with varying durations (1 year or 5 years).
- Gratuitous permits for materials like sand, gravel, and guano have specific area and duration limitations.
- Gemstone Gathering Permit: Valid for 1 year, renewable.
Conclusion
- Mining plays a crucial role in the global economy and infrastructure development but requires careful management to minimize environmental impacts and support local communities.
