How can we reduce soil erosion during surface mining of coal?

BMPs may include diverting runoff water away from or establish- ing vegetative cover on disturbed land to prevent erosion, or installing silt fences or sedimentation ponds to remove sus- pended sediment from runoff before it leaves disturbed areas (Conrad, 1990).

Can coal reduce erosion?

Land subsidence in coal mining can induce several types of ecological environmental destruction, such as land destruction, soil erosion, and vegetation degeneration, further altering the soil properties. Studies have shown that land subsidence significantly influences soil properties.

How does coal mining affect erosion?

Deforestation and Erosion: As part of the process of clearing the way for a coal mine, trees are cut down or burned, plants uprooted and the topsoil scraped away. This results in the destruction of the land (it can no longer be used for planting crops) and soil erosion.

How does surface mining cause soil erosion?

Strip mining destroys landscapes, forests and wildlife habitats at the site of the mine when trees, plants, and topsoil are cleared from the mining area. This in turn leads to soil erosion and destruction of agricultural land. When rain washes the loosened top soil into streams, sediments pollute waterways.

How can we reduce erosion?

How does coal affect soil?

The pH of the coal mine dump contaminated soil decreased with an increase in contamination. Both the SOM and CEC values decreased, which increases the availability of elements, by providing more binding sites in the soil.

How does mining contaminate soil?

Particulate matter is released in surface mining when overburden is stripped from the site and stored or returned to the pit. When the soil is removed, vegetation is also removed, exposing the soil to the weather, causing particulates to become airborne through wind erosion and road traffic.

What causes soil erosion?

What Causes Erosion? Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.

How coal mining causes land degradation?

As a typical underground mining zone in semi-arid areas, coal exploitation may cause lots of adverse impact on land and brings negative consequence, which leads to land degradation, including cracks and fissures, unstable slope, landslides, and aquifer losses.

How does surface mining affect the soil?

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.

How do humans contribute to soil erosion?

These causes include road erosion, house construction, steep slope cultivation, tourism development, and animal trampling. These activities destroy surface vegetation and increase the potential for soil loss through exposed swallow holes (karst fissures).

Why does surface mining of coal typically cause more environmental harm than does subsurface mining?

The groundwater from the mines is more acidic than surface waters and disrupts ecosystems by changing the pH conditions of soil and water sources.

What are some of the ways in which coal mining can harm the surrounding environment?

Mining Adds Harmful Pollution to Our Air:

There are two main sources of air pollution during the coal production process: methane emissions from the mines, which contribute to global warming pollution, and particulate matter (PM) emissions, which can cause significant respiratory damage as well as premature death.

Is coal good for soil?

More important, unlike other organic fertilizers, charcoal is very stable and it will not decompose to carbon dioxide. So once applied, it will stay in soil for hundreds to thousands of years. So to summarize, the high stability and porosity make charcoal a better fertilizer than other organic materials.

Is burning of coal pollutes the soil?

Explanation: Burning of coal doesn’t pollutes in soil.

How mining can contaminate ground and surface water sources?

Mining companies generally use chemical compounds such as sulphuric acid or cyanide to separate their respective target minerals from the ore. Contamination occurs when these chemicals are leached, leaked, or spilled from the mining area into the nearby bodies of water.

Why do we need to prevent soil erosion?

When the topsoil is eroded from an area, that area loses its most nutrient-rich layer, and therefore soil quality is reduced. Poor soil quality means smaller crop yields and may even wash away seeds and small plants.

How does mining contribute to the spoilage of land?

These overburden dumps are known as mine spoil. This drastically system is highly prone to erosion and causes contamination of rivers and adjoining agricultural lands with harmful substances leached out from it through rain water.

What should be done to areas degraded by mining activities?

After removal of mining waste, the topography has to be rebuilt with an inert material. Then, topsoil has to be constructed and a riparian forest re-established. To avoid erosion processes of the newly constructed soil, the document also determines the necessity to quickly establish vegetation cover.

Why does surface mining pose more environmental problems than underground mining?

Surface mining requires large areas of land to be temporarily disturbed. This raises a number of environmental challenges, including soil erosion, dust, noise and water pollution, and impacts on local biodiversity.

What is one advantage of surface mining?

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.

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

Both surface mining and underground mining risk causing severe water pollution. Surface mining causes more destruction of land ecosystems than underground mining. Metals can be extracted from their ores in several different ways, two of which are carbon reduction and electrolysis.

How does mining destroy the environment?

Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes.

How are the health impacts of surface mining different from those of underground mining?

In 2015, there were 2.08 deaths per 10,000 workers in underground mines, but about one-third of that number in surface mines. In terms of nonfatal injuries, there were 284.3 nonfatal lost-time injuries per 10,000 workers in underground mines, but less than half of that, 125.6 per 10,000 workers, in surface mines.

How does underground mining affect the environment?

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.

How can soil erosion be prevented in Brainly?

1.) Intensive cropping Crops keeps the soil binded. 2) Sowing grasses and planting xerophytes Sowing grasses on barren soil or planting of xerophytes will bind the loose soil. 3) Terrace farming (terracing) In terracing the slopes are divided into a number of flat fields to slow down the flow of water.

What steps can be taken to control soil erosion Brainly?

Following steps are taken to control the soil erosion in hilly areas: (i) Contour ploughing: this refers to ploughing along contour lines. (ii) Terrace farming: construction of steps along the hilly areas by cutting the rock layers to reduce the flow of rivers. (iii) Plugging of gullies to prevent gully erosion.

In what two ways can people prevent erosion Brainly?
