Question

how does mining affect rock layers?​

Answer 1

Answer:

The change in overburden structure resulting from mining causes horizontal tension on the surface, while vertical shear occurs due to the movement of overburden in the vertical direction.

Answer 2

Environmental issues can include erosion, formation of sinkholes and loss of biodiversity.

Explanation:

• The change in overburden structure resulting from mining causes horizontal tension on the surface while vertical shear occurs due to the movement of overburden in the vertical direction.
• Contamination of soil groundwater and surface water by chemicals from mining processes.
• Contamination resulting from leakage of chemicals can also affect the health of the local population if not properly controlled.
• Across the world mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water all of which can lead to health issues in local .
