The effects can result in erosion, sinkholes, loss of biodiversity , or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also affect the atmosphere from the emissions of carbon which have an effect on the quality of human health and biodiversity.
Why does mining have such an impact on the environment?
Mining has a large impact on the environment because minerals are contained within the Earth . Earth must be removed in order to extract the minerals. When the minerals are close to the surface, the earth is removed, causing destruction to the shape of the land and the flora and fauna living in that area.
Does reclamation restores an environment affected by mining to a state where it can sustain its ecosystem?
Reclamation restores an environment affected by mining to a state where it can sustain its ecosystem.
How does mining affect local populations?
The amount of minerals that can be extracted in a certain location can be exhausted after sometime. Large scale mining can provide temporary local employment but it also competes for the use of land, water, forests and other local resources against local communities and most likely the local communities will lose.
Which type of mining is least harmful to the environment?
Placer mining can be less damaging to the environment than surface mines, as the sediment is returned to the water after the minerals have been extracted.
Which of the following is not environmental impacts of mining?

What are the bad effects of mining?
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 ...
What are the impacts of mining on society economy and environment?
The main impact of mining and oil development on these ecosystems is the alteration of the water regime, especially lowering of the water table and depletion of groundwater . These impacts may result in increased salinization of the soil and erosion, which eventually lead to a decline in vegetation and wildlife species.
How does salt mining affect the environment?
Environmental impact rock salt mining by dissolution manifests in various ways: surface and ground waters may be affected by discharges of contaminated water , air can be affected by emissions of particulate matter, and subsidence of surrounding terrain can affect inhabited areas.
Mining tends to raise wage levels , leading to displacement of some community residents and existing businesses, and elevated expectations (Kuyek and Coumans, 2003). Mining may also trigger indirect negative social impacts, such as alcoholism, prostitution, and sexually transmitted diseases (Miranda et al., 1998).
Which type of mining is best for the environment?
In situ mining (see mining solution page) can be more environmentally friendly than underground mining and is cheaper than many mining methods (Ulmer-Scholle, 2008).
Which type of mining is better for the environment?
In situ mining , for example, can be more environmentally friendly than underground mining and is cheaper than many mining methods.
What is the best type of mining?
Surface mining is best suited to extract minerals that are close to the surface of the earth. It is also usually a more cost-effective mining method compared to underground mining. Common minerals extracted using surface mining are some of the most mined including coal, iron and bauxite.
