Environmental effects of mining can occur at local, regional, and global scales through direct and indirect mining practices. 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.
What are the environmental impacts of underground mining?
Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.
What are 3 harmful side effects of mining on the Earth?
Mine exploration, construction, operation, and maintenance may result in land-use change, and may have associated negative impacts on environments, including deforestation, erosion, contamination and alteration of soil profiles, contamination of local streams and wetlands, and an increase in noise level, dust and …
What are the problems associated with underground mining?
Mining has several adverse impacts including air, water and soil pollution, socio-economic problems and effect on wildlife population and their behaviour. … As the deposits near the surface are exhausted underground mining may become cost competitive.
What are the environmental effects of mining?
Environmental issues can include erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes. In some cases, additional forest logging is done in the vicinity of mines to create space for the storage of the created debris and soil.
Is underground mining environmentally friendly?
In regard to the environmental impact of underground mining, the NSW Minerals Council noted that: Subsidence from underground mining will have some environmental effects – as do most kinds of development. The question that needs to be answered is one of the acceptability of impacts.
What are the environmental effects of mining on plants and animals?
Mining affects species by destroying, fragmenting, and degrading natural habitats, releasing toxic wastes (Gentes et al., 2007) and altering land-use dynamics in mined regions (Sonter et al., 2014).
What are the disadvantages of mining?
Disadvantages of Mining
- Mining can lead to soil pollution.
- Groundwater pollution.
- Depletion of natural resources.
- Mining implies the destruction of habitats.
- Endangerment of species.
- Loss of biodiversity.
- Landslides become more likely.
What are the environmental impacts of mining in Australia?
Mining poses a variety of environmental risks, including potential impacts on ground and surface water quantity and quality, air quality, biodiversity, landscape stability and climate change. Australia’s mining sector has the skill, technology and motivation necessary to manage and mitigate these risks.
How pollution is caused due to mining activities?
The heavy metal mine water penetrates into the groundwater through surface seepage, changing the pH of the water body, affecting the self-purification ability of the water body, and causing serious pollution damage to the surrounding rivers and farmland.
Environmental and social impacts are divided into waste management issues, impacts to biodiversity and habitat, indirect impacts, and poverty alleviation and wealth distribution. … Disposing of such large quantities of waste poses tremendous challenges for the mining industry and may significantly impact the environment.
What are the consequences of moving from underground mining to surface mining quizlet?
Earth must be removed in order to extract the minerals. When the minerals are close to the surface, the earth is removed, causing destruction to the shape of the land and the flora and fauna living in that area.
What was the environmental impact of mining quizlet?
Mining can have bad effects on surrounding surface and ground water if protective measures are not taken. The result can be unnaturally high concentrations of some chemicals, such as arsenic, sulfuric acid, and mercury over a significant area of surface or subsurface.
