Q. Mineral resources are fundamental to the country’s economy and these are exploited by mining. Why is mining considered an environmental hazard? Explain the remedial measures required to reduce the environmental hazard due to mining.

Introduction:
Mining, while vital for economic growth and industrialisation, disrupts ecosystems and degrades land, making it a significant environmental hazard.

Why Mining is an Environmental Hazard

1. Land Degradation

Deforestation, topsoil removal
Open-cast mining → landscape alteration, land subsidence

2. Water Pollution

Acid mine drainage (heavy metals like lead, arsenic)
Contamination of surface & groundwater

3. Air Pollution

Dust (PM2.5, PM10), toxic gases
Health issues: respiratory diseases

4. Biodiversity Loss

Habitat destruction, fragmentation
Threat to flora & fauna in forest/mineral-rich areas

5. Soil Erosion & Desertification

Loss of fertility due to removal of topsoil

6. Noise & Vibration

Blasting affects wildlife & nearby settlements

7. Waste Generation

Overburden, tailings → toxic accumulation

Remedial Measures to Reduce Environmental Hazards

1. Sustainable Mining Practices

Scientific mining, controlled blasting
Underground mining where feasible

2. Environmental Impact Assessment (EIA)

Mandatory clearance before projects
Monitoring compliance by Ministry of Environment, Forest and Climate Change

3. Land Reclamation & Afforestation

Backfilling, soil restoration
Compensatory afforestation

4. Water Management

Treatment of mine water
Prevention of acid mine drainage

5. Air Pollution Control

Dust suppression (water spraying, green belts)
Use of cleaner technologies

6. Waste Management

Safe disposal of tailings
Recycling of mining waste

7. Community & Health Measures

Rehabilitation & resettlement (R&R)
Health monitoring of local populations

8. Regulatory Framework

Sustainable mining guidelines by Indian Bureau of Mines
District Mineral Foundation (DMF) for local welfare

Way Forward

Adoption of green mining technologies
Strict enforcement of environmental norms
Community participation & transparency
Use of remote sensing for monitoring

Conclusion:
Balancing mineral extraction with environmental sustainability requires strict regulation, technological innovation, and responsible mining practices.
