Strip mining before during after

More information
During strip mining, one type of surface mining, workers remove the layer of topsoil along with excess soil and rock that overlies caches of minerals near the surface. Once workers finish mining, they usually lay down nutrient-poor soil, called overburden, instead of nutrient-rich topsoil that is more difficult to store during the lengthy mining process, according to Chris Barton of the Appalachian Regional Reforestation Initiative. The overburden soil is also highly acidic, at a pH of 2 or 3, and so doesn't support many trees, bushes or other flora. Furthermore, dumping loose topsoil onto mountainous areas, such as in Appalachia, can cause landslides, and uncompacted soil can run off and clog waterways, setting the stage for flash floods. To offset such difficulties, those involved in reclamation have a number of tricks in their arsenal.

Chapter 2: The Environmental Effects of Strip Mining - The Strip Mining Handbook

Mine reclamation is the process of restoring land that has been mined to a natural or economically usable state. Although the process of mine reclamation occurs once mining is completed, the planning of mine reclamation activities occurs prior to a mine being permitted or started. Mine reclamation creates useful landscapes that meet a variety of goals ranging from the restoration of productive ecosystems to the creation of industrial and municipal resources. In the United States, mine reclamation is a regular part of modern mining practices. As part of the life cycle of a surface coal mine , completed mine areas must undergo rehabilitation.

How they arise and how their effects can be mitigated Overview Unregulated mining has the potential to release harmful substances into the soil, air, and water. Mission proposes that governments enforce regulations on companies and use cutting-edge technology to reduce the damage from mining-related sources. As more mines open in countries with varying levels of environmental protection, it is increasingly vital that safeguards established by the Strategic Minerals Association SMA are in place before operations proceed see the international regulation page. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
