what is the most likely consequence of open pit mining on plant life?
What consequence does open-pit mining most likely have 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 some of the effects of open-pit mining?
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. As such, a repeatable process to evaluate these effects primarily aims to diminish them.
How does open-pit mining affect the environment?
Open-pit mining includes blasting of soil and vegetation to access underground ore layers or coal seams [17]. Consequently, this method produces large volumes of mining waste, including soil and overburden, which increase the vulnerability of mining environments to soil erosion and pollution.
How Surface Mining affects plant life?
Surface mining destroys all plant life in the area the mine occupies. … After the surface mine is no longer productive, plants may eventually return to the area, but typically some human efforts at reclamation are required to restore the environment to some level of productivity.
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.
Is open pit mining bad?

Open-cast mining changes geological, hydrological and geotechnical conditions. It influences the existing ecological system and landscape. The dust and noise affect not only the atmosphere and soil, but also the whole human living space in the exploited territories.
What are some disadvantages of underground mining?
Although there are opponents and proponents of underground mining, the disadvantages include destruction of land, surface subsidence, abandoned shafts, extensive surface spoil heaps, mine explosions, collapses and flooding. That doesn’t incorporate the costly price tag that comes with underground mining.
What are the effects of mining in plants and animals?
Runoff from mines can also contaminate local water supplies such as rivers, creeks and lakes. This contamination can cause the death of wildlife and/or cause genetic mutations in offspring.
How does mining affect people’s lives?
Mining affects people’s health directly, when people work in dangerous conditions and are exposed to toxic chemicals . It also affects people’s health through the social problems it brings . Mining towns and camps develop quickly, with little planning or care .
How does underground mining affect the environment?
Underground mining causes huge amounts of waste earth and rock to be brought to the surface – waste that often becomes toxic when it comes into contact with air and water. It causes subsidence as mines collapse and the land above it starts to sink. … Coal mining produces also greenhouse gas emissions.
Why does mining have such an impact on the environment quizlet?
Mining has a large impact on the environment because minerals are contained within the Earth. 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.
Which type of mining is least harmful to the environment?
Sub-Surface mining is likely the least harmful to the environment.
How do mine tailings damage the environment?
Tailings. Mining processes produce an excess of waste materials known as tailings. … Tailings have great potential to damage the environment by releasing toxic metals by acid mine drainage or by damaging aquatic wildlife; these both require constant monitoring and treatment of water passing through the dam. See also what is the most important line of latitudeWhat would be the reason why most open pit mining is converted into underground mining?
This transition from open-pit to underground begins when open-pit mines are exhausted or inaccessible; meaning, they have either been depleted of minerals, rocks, and resources, or they are unfeasible to build upon.
What do you understand by open pit mining?
Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels.What are the positive and negative effects of mining?
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: … exposing them to harassment by mine or government security.What are some pros and cons of mining?
Top 10 Mining Pros & Cons – Summary List| Mining Pros | Mining Cons |
|---|---|
| Job opportunities related to mining | Can lead to significant soil pollution |
| Important for the development of a region | Groundwater pollution |
| Higher tax income for governments | Habitat destruction |
| Mining is crucial for technological progress | Biodiversity loss |
What is the biggest environmental risk of mining quizlet?
Mining causes disturbed lands, oil spills and blowouts, and mine waste dumping. Processing produces solid wastes, pollutes the air, water, and soil, and produces radioactive material, using this causes thermal water pollution, solid and radioactive wastes, and health hazards.
How does mining affect the hydrosphere?
The effect of the coal-mining complex on the hydrosphere causes a change of water regime of the territory—pollution of ground and waste waters with products of physical and chemical weathering of subsurface rocks.
What are the environmental and social impacts of mining?
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 is the advantage and disadvantage of underground mining?
Explanation: Shallow mineral or coal deposits can be economically mined by open-pit or strip mines. However, with deeper mineral or coal deposits it becomes very costly to remove a great deal of overburden in these kinds of settings. So, in these cases underground mining is more cost effective.
What are the advantages and disadvantages of surface mining over underground mine?
Surface mines offer advantages and disadvantages when compared to underground mining. Amongst the advantages are that it is cheaper, can recover more of the resource (usually up to 100% within the mining excavation), is safer and can use larger-scale mining equipment offering higher production rates.Is open pit mining better than underground mining?
After the mineral deposits have been exposed, the area is drilled, fractured and the mineral extracted. This method has a high recovery rate when compared to the underground, as 90 percent of mineral deposits are recovered. Overall when compared to other methods, open-cut is much safer. See also why are small populations more prone to genetic diseaseHow does mining affect the life of plants and animals of any particular area?
