Case Study:

In the mineral-rich region of Dhanbad in Jharkhand, coal mining has been a major economic activity for decades. The region produces nearly 25% of India’s total coal output and provides employment to thousands of workers. Both open-cast and underground mining methods are used, depending on the depth and quality of coal deposits.

Over the years, coal extraction increased by 35% due to rising energy demand from industries and power plants. However, this rapid expansion led to several environmental and social challenges. Open-cast mining caused large-scale deforestation and land degradation, while underground mining resulted in land subsidence in nearby villages.

A survey showed that air pollution levels in the region increased by 40%, affecting the health of local residents. Water sources were also contaminated due to mining waste. To address these issues, the government introduced regulations such as mandatory land reclamation, afforestation programs, and stricter pollution control measures.

Additionally, mining companies were directed to adopt sustainable practices and invest in community development projects like healthcare and education. Despite these efforts, illegal mining and lack of proper monitoring remained significant challenges.

This case highlights the importance of balancing economic development with environmental protection and sustainable resource use. It also emphasizes the need for responsible mining practices and effective policy implementation.
