Frequent question: How does mining cause environmental disasters explain and elaborate your answer?

As mining produces copious amounts of waste water, disposal methods are limited due to contaminates within the waste water. Runoff containing these chemicals can lead to the devastation of the surrounding vegetation. The dumping of the runoff in surface waters or in a lot of forests is the worst option.

How does mining cause environmental disasters?

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

Why does mining cause water pollution?

Water running through mine tailings can become polluted.

Mine drainage is metal-rich water formed from a chemical reaction between water and rocks containing sulfur-bearing minerals. … The acid runoff further dissolves heavy metals such as copper, lead, mercury into groundwater or surface water.

How does underground mining affect the environment?

Underground mining causes huge amounts of waste earth and rock to be brought to the surface – waste that often becomes toxic when it comes into contact with air and water. It causes subsidence as mines collapse and the land above it starts to sink. … Coal mining produces also greenhouse gas emissions.
