What are 2/3 environmental problems caused by open pit mining?
The effects 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 affect the atmosphere from the emissions of carbon which have an effect on the quality of human health and biodiversity.
What are the disadvantages of open pit mining?
1.1 Features, technical and economic indicators of open pit development
| Advantages | Disadvantages |
|---|---|
| High production rate (essentially unlimited, although small surface mines also possible) | Limited by stripping ratio |
| Lowest cost along with open cast mining | High capital investment associated with large equipment |
Why is open pit mining so devastating to the environment?
Why is open pit mining so devastating to the environment? Open pit mining is so devastating to the environment because it exposes dangerous chemicals buried in the earth’s crust.
What environmental impacts does mining have?
Mining: Environmental Impacts Mining can pollute air and drinking water, harm wildlife and habitat, and permanently scar natural landscapes. Modern mines as well as abandoned mines are responsible for significant environmental damage throughout the West.
What is the most likely consequence of open pit mining on plant life?
The soil looses it’s fertility. This converts the mining site into a barren land. Therefore, the complete loss of plant life in the area occupied by the surface mine is the most likely consequences of open pit mining on plant life.
What are the environmental and social impacts of mining?
Some of the negative impacts of mining are loss of vegetation cover, mass destruction of water bodies, loss of biodiversity, land-use changes and food insecurity, increased social vices and conflicts, high cost of living, and air pollution.
What consequence does open pit mining most likely have on plant life Brainly?
In the multiple-choice, the most likely consequence of open-pit mining on plant life is c. The complete loss of plant life in the area occupied by the…
How does mining positively and negatively impact local communities?
Mining can impact local communities both positively and negatively. While positive impacts such as employment and community development projects are important, they do not off-set the potential negatives. We have found mining can negatively affect people by: forcing them from their homes and land.
What are environmental impacts of mining?
Is the most likely consequence of open pit mining on plant life?
Why does mining have such an impact on the environment? Because minerals are within the Earth’s surface, extraction causes destruction. How is coal extracted from mountaintop removal mines?
How does mining harm the environment?
Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local …
What are the consequences of open pit mining?
Mining 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.
What effect does mining have on the environment?
Mining affects the environment by exposing radioactive elements, removing topsoil, increasing the risk of contamination of nearby ground and surface water sources, and acidification of the surrounding environment.
What are the environmental effects of opencast mining?
The major environmental concerns around opencast mining include the generation of dust through blasting, raw-ore haulage and processing activities, which have serious impacts on the air quality at opencast mines and on health, and the ambient air quality surrounding opencast mines.
What are the environmental issues caused by mining?
Environmental Impacts Of Mining Air Pollution. Air quality is adversely affected by mining operations. Water Pollution. Mining also causes water pollution which includes metal contamination, increased sediment levels in streams, and acid mine drainage. Damage To Land. Loss Of Biodiversity.
