Environmental Impact of Mining:

  • Mining activities can cause significant environmental damage.

Green Initiatives for Sustainable Land Use:

  • Efforts are underway to manage land resources after mining for long-term benefits, but these initiatives require further development.

  • The current focus is on restoring mined lands using scientific methods.

  • Future Vision: Establishing community-friendly land uses like restored forests and eco-parks is planned for the future (according to a report by the Ministry of Coal).

Mitigating Impacts During Mining:

  • Overburden Management: In open-cast mines, removing layers of soil and rock (overburden) is necessary to access the coal.

  • Overburden Reuse: This overburden is processed and used for other purposes to minimize environmental impact.

  • Afforestation Efforts: Planting trees (afforestation) is another strategy used in some areas to counteract the environmental damage from mining.
