Underground Mining for Meeting Environmental Concerns

 · All mining operations have a negative effect on the environment but the high volume of material involved in surface mining makes the impact on the environment very acute. Underground mining can be considered to be more acceptable than surface mining from environmental and social perspectives since, it often has a smaller footprint than an open.

What is Strip Mining? Methods and Impact

 · What is Strip Mining? Surface mining, counting strip mining, mountaintop removal mining and open-pit mining, is a wide classification of mining where soil and rock covering the mineral source (the 'overburden') are gotten rid of, unlike underground mining (or deep mining) where the overlying rock is kept in place, and the mineral is taken out through shafts or tunnels.

How Does Mining Affect the Environment?

 · Different types of mining have various impacts on land. For example, strip mining results in the clearing of trees, plants and topsoil [2]. One effect of this type of mining on the environment is the pervasive problem of soil erosion, which in turn leads to the pollution of waterways.. Another destructive type of mining is underground coal mining.
