Impacts of strip mining: Strip mining destroys landscapes, forests and wildlife habitats at the site of the mine when trees, plants, and topsoil are cleared from the mining area. This in turn leads to soil erosion and destruction of agricultural land. When rain washes the loosened top soil into streams, sediments pollute waterways.

Environmental Impact – Water Resources. The waste sludge from coal mining is a toxic brew of mercury, diesel and other chemicals that are placed into unlined slurry dams, which in turn seeps into the groundwater and eventually finds it way into the drinking water supply.
Strip Mining - an overview | ScienceDirect Topics
The mining of bauxite for an alumina product has the same kind and degree of environmental impact as imposed by any strip mining operation. These effects may be minimized by spoils replacement and aesthetic contouring, as well as by the replanting of hardy grasses and shrubs, where appropriate.

Mining | Environmental Issues
Strip mining. Strip mining involves scraping away earth and rocks to get to coal buried near the surface. In many cases, mountains are literally blasted apart to reach thin coal seams within, leaving permanent scars on the landscape as a result. Strip mining accounts for about 40 percent of the world’s coal mines but in some countries, such ...
Effects Of Mining on the Environment and Human …
While underground mining, which allows coal companies to extract deeper deposits of coal, is viewed as less destructive than strip mining, the effects of mining widespread damage to the environment. In room-and-pillar mines, columns of coal are left to support the ground above during the initial mining process, then they are often taken out and the mine is left to collapse, which is known as ...
Environmental impact of mining - Wikipedia
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts 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 have an impact on the atmosphere from the emissions of carbon which have ...
Open Pit Mining Pros & Cons | Sciencing
Open pit mining is also called strip mining because the extraction process destroys vegetation, reduces habitats and pollutes the environment. Mining proponents argue that the process is more efficient, cost effective and safer than shaft mining. Environmental regulations help mitigate damage.
The Environmental Science of Surface Mining - …
Strip mining. Strip mining, as the name describes, is a process of removing rock and soil in strips to get to the valuable mineral ores below.After miners extract the resources, they put back the leftover rock and soil, called mining spoils or tailings, to fill in the hole.. One way to replace tailings is to simply dump them; luckily, U.S. regulations require mining companies to replace ...

If no action is taken to remediate the many environmental problems inherent to modern mining, the end cost for governments and communities would be devastating. Already mines in China release 9,600 to 12,000 cubic meters of toxic gas containing flue dust concentrate, hydrofluoric acid, sulfur dioxide, and sulfuric acid for each ton of rare earth elements produced.
