1) Underground mine — ground subsidence: tunnels and voids can cause the surface to sink or collapse, damaging buildings, roads, and ecosystems above.
2) Underground mine — groundwater contamination and acid mine drainage: exposed minerals can make water acidic and carry heavy metals into wells, streams, and rivers.
3) Surface mine — habitat loss and landscape destruction: removing soil and rock destroys plant and animal homes and changes the land permanently.
4) Surface mine — erosion and water pollution: exposed soil and waste rock wash into streams, increasing sediment and pollutants that harm aquatic life and water quality.
