Mar 04, 2020nbsp018332Some mining techniques like in-situ leaching, which uses acid and water to remove minerals from a site without significantly disturbing the surface have much less environmental impact. In-situ mining techniques can use less water than open-pit mining and underground mining, and also reduce the risk of releasing ore dust into the atmosphere.

Mar 12, 2017nbsp018332negative effects of surface mining on the environment. it is important to know that there are three key ways in which coal extraction and in particular surface mining affect wildlife and biodiversity. the direct impact of extraction activity
Surface mining can have severe environmental effects. the process removes all vegetation, destroying microflora and microorganisms. the soil, subsoil, and strata are broken and removed. wildlife is displaced, air quality suffers, and surface changes occur due to oxidation and topographic changes.

In surface mining, the ore is accessed directly from the earths surface, and contact is maintained with the surface throughout the operation. underground or subsurface mining is accomplished with the help of tunnels going into the earth, and does not occur on the surface. working principle
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.
