Metal mining provides us with materials essential for modern life. But mining also devastates communities, water and the environment. Massive landslide at the Bingham Canyon mine in Utah. Photo: Deseret News. Modern Mining: Permanent Landscape Damage. Massive open pit mines are the most common type of industrial metal mine.
But many seem convinced that open pit mines are ugly blots on the landscape. Could this just be conditioning? ... This is one of the biggest open pit mines in the world, operated by Chilean state owned Codelco . ... The beauty of this human constructed mining landscape is protected. It was declared a UNESCO World Heritage site in 1997.
Ground water constitutes a significant operational problem and potential hazard in open-pit and underground mining. The pressure of ground water in geologic discontinuities adversely affects the safety of height and slope angles of open-pit mines, justifying measures to reduce ground-water pressures in their vicinity. The principal hazard in underground mining and tunneling …
Open pit mining (also known as strip mining) is the process of extracting ore, minerals and/or fossil fuels that occurs on the surface of a particular mining site. When considering all the mining operations in the world, at least 40 percent of mining takes place at the surface reports Greenpeace International.

Among the major concerns about open-pit mining are the change in landform, the generation of an acid mine drainage, and the deprivation of water supply. All these, however, can be reversed, mitigated, if not totally avoided, with the proper engineering solutions, using advances in technology.
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.
The creation of landscape blots like open pits and piles of waste rocks due to mining operations can lead to the physical destruction of the land at the mining site. Such disruptions can contribute to the deterioration of the area's flora and fauna.

Open-pit mining is a type of surface mining used to extract coal, gold, and other minerals. It creates immense water and air pollution, disfigures landscapes, and destroys habitats.
Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure 8.8. Open-pit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.
Open-pit mining is a type of surface mining used to extract coal, gold, and other minerals. It creates immense water and air pollution, disfigures landscapes, and destroys habitats.
Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in areas nearby.
Why is open-pit mining a problem for the environment? M ining is widely regarded as having adverse effects on environment of both magnitude and diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and open-pit mining in particular.
Strip mining, underground mining, open pit mining, heap leaching, and brine mining might all be more environmentally damaging forms of mining … Strip Mining [and underground mining might both have] extensive environmental impact … – environment.co.za Open pit and underground mining can have their issues …
Open-cast mining is an estimated 30% cheaper than deep mining, thus providing an economic incentive for those concerned mostly with costs. In 1984, it cost £27.55 to produce a tonne of open-cast coal in the UK, and in 1990, the cost increased only to £27.60.
