Mineral resources are fundamental to the country's economy and these are exploited by mining. Why is mining considered an…

Mining drives industrialization and infrastructure, contributing vital raw materials to India's economy. However, unscientific and intensive extraction causes severe ecological disruption through distinct causal pathways.

Causes of Environmental Hazard

Land Degradation: Topsoil removal and excavation in open-cast mining cause extensive deforestation and permanently destroy agricultural productivity. Underground mining destabilizes geological strata, triggering land subsidence and surface collapse.

Water Pollution and Depletion: Exposure of excavated sulfide minerals to air and water generates Acid Mine Drainage (AMD), which leaches toxic heavy metals like arsenic and mercury into rivers and aquifers. Massive dewatering for deep mining lowers water tables, depriving local communities of potable water.

Air Pollution: Drilling, blasting, and haulage release massive loads of particulate matter (PM₂.5, PM₁₀) and toxic coal dust. In intensive belts like Jharia and Dhanbad, persistent fugitive emissions cause severe chronic respiratory illnesses among populations.

Biodiversity Loss: Mining activities fragment critical wildlife corridors and destroy habitats in ecologically sensitive zones, including the Western Ghats, the Aravallis, and the Northeast, threatening endemic flora and fauna.

Remedial Measures

Ecological and Operational Interventions: Rigorous compliance with Environmental Impact Assessments (EIA) must govern all project life cycles. Implementing progressive mine closure alongside active extraction facilitates concurrent bio-reclamation of overburden dumps using native vegetation. Deploying cleaner extraction technologies, such as continuous surface miners and zero-liquid-discharge effluent treatment plants, curbs particulate emissions and Acid Mine Drainage.

Legal and Institutional Frameworks: The Indian Bureau of Mines (IBM) must strictly enforce the Sustainable Development Framework (SDF) alongside the Star Rating system to incentivize ecological compliance. Furthermore, the MMDR Act, 2015, mandates utilizing District Mineral Foundation (DMF) funds to finance environmental remediation, watershed restoration, and community healthcare.

Adopting green mining techniques and circular economy principles is essential to harmonize mineral extraction with long-term ecological sustainability.
