What environmental impacts are caused by both surface mining and underground mining?

What environmental impacts are caused by both surface mining and underground mining select the two correct answers?

In many cases, contaminants like acids or heavy metals leach from the overburden into groundwater or become part of runoff into local waterways. In some cases of mountaintop removal mining, all of the removed material fills nearby valleys, completely clogging small creeks and streams.

What are some environmental impacts of both surface and subsurface mining?

Surface mining removes ore deposits that are close to the surface, and subsurface mining removes minerals that are deep underground. While mineral use is very important to us, there are also many environmental impacts, such as erosion, air and water pollution, land destruction and harm to mine workers.

What are the environmental problems with surface mining and underground mining?

Surface mining (another name for “strip mining”) can severely erode the soil or reduce its fertility; pollute waters or drain underground water reserves; scar or altar the landscape; damage roads, homes, and other structures; and destroy wildlife.

What environmental impacts are caused by the mining and use of coal?

There are significant environmental impacts associated with coal mining and use. It could require the removal of massive amounts of top soil, leading to erosion, loss of habitat and pollution. Coal mining causes acid mine drainage, which causes heavy metals to dissolve and seep into ground and surface water.

What are the effects of underground subsurface mining?

Subsurface mines produce large amounts of environmentally hazardous acid mine drainage. To keep the underground system of tunnels and mine shafts clear, mining companies have to pump out large amounts of water, which go into surface ecosystems.

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.

What are 3 environmental problems caused by open pit mining?

However, mining processes can cause various environmental problems, including deforestation, soil erosion, destruction of the natural landscape, landslides, water-level reduction and surface water depletion through dewatering, as well as water and soil pollution from mining waste and tailing dust [3–7].

What are three environmental problems of underground mining?

Bad mining practices can ignite coal fires, which can burn for decades, release fly ash and smoke laden with greenhouse gasses and toxic chemicals. Furthermore mining releases coal mine methane, a greenhouse gas 20 times more powerful than carbon dioxide.

Why does mining have such an impact on the environment?

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.
