Surface damage caused by mining

1.

It will certainly have an impact on the earth. The most affected are environmental st pollution, water loss, soil quality change and species rection

First, the st pollution caused by mining is very large after the ore is mined, there will be a lot of harmful st. The most important thing is that the ore has to be stripped and selected after mining, which will proce a lot of st in the process. Slag also has a great impact on the environment. At present, there is no perfect way to deal with slag. Slag will fly with the wind in windy weather. This causes air pollution and increases the number of inhalable particles{ RRRRR}

through the above analysis, it can be concluded that if the earth's mineral resources are continuously mined, the impact on the earth is very large. Although studies have shown that ore mining is only on the surface, not deep enough to directly affect the earth. But the impact on the earth's surface is direct, which indirectly destroys the earth's ecology and affects the earth from all aspects

2. The impact of mining proction on the environment includes soil erosion, land subsidence caused by mines, destruction of biodiversity and groundwater pollution caused by wastewater containing chemicals in the mining process
the state has strict laws and regulations on environmental protection and restoration of the surface state of mining instry, which ensure that the mining area should be restored to its original state, or even better than the environment before mining. In countries where the past mining methods are not strictly restricted, the mining instry will cause irreparable harm to the environment and affect human health.

1、 What is the harm of open-pit copper mining to the environment: open pit mines are easy to cause water pollution, geological disasters, solid waste pollution, air pollution and water environment pollution

treatment and protection methods: develop new energy, rece mining, reasonable mining

Secondly, the loose surface will cause soil erosion; thirdly, it will cause soil acidification. Because coal contains a lot of sulfur, the mining of coal will cause a lot of sulfur to fuse into the water, and then cause soil acidification, It will cause debris flow and landslide

treatment and protection methods: develop new energy, rece mining, reasonable mining

Thirdly, what harm does iron mining do to the environment: soil erosion, land subsidence caused by mines, destruction of biodiversity and pollution of groundwater caused by waste water containing chemicals in mining process

treatment and protection methods: develop new energy, rece mining and exploit reasonably

extended data

1. What is water pollution

when the pollutants entering the water body exceed the environmental capacity or self purification capacity of the water body, the water quality will deteriorate, thus destroying the original value and function of the water body, which is called water pollution. There are two reasons for water pollution: one is natural, the other is man-made. The special geological conditions make a large number of chemical elements enrich, natural plants proce some harmful substances when they decay, and rainwater falls to the ground and flows into the water body with various substances, all of which belong to natural pollution

4. Hello, the so-called mining is ore development or ore mining project, environmental pollution and ecological impact coexist. There are many aspects of its impact, simply from the four aspects of water, air, disease and land, it can be summarized as follows:
water --- A. improper disposal or unreasonable stacking of earth and stone, blocking surface runoff and blocking the river channel.
b the mine and open pit drainage water in the process of proction and operation contains a lot of ore deposits (such as coal slime of coal mine)
for example, it contains heavy metals and other pollutants (depending on the ore type and ore type)
C. mineral processing wastewater, coal washing wastewater and tailing pond effluent pollute the receiving water< Mining may lead to surface water leakage, forming groundwater funnel, water level drop or leakage, affecting other instrial, agricultural, ecological and domestic water in the area.
e tailings reservoir leakage and mine reinjection water may pollute groundwater
air-a. ore st and st generated in the process of ore construction, mining, crushing, screening, grinding and ore transportation lead to the decline of regional air quality
B. polluted air (including methane, carbon dioxide, etc.) in mine ventilation shaft site
C. improper treatment of gas drainage can cause gas odor, even gas leakage and explosion accidents
disease -- (known as population health in EIA)
A. construction workers and mining and dressing personnel come from all over the country, and there is the problem of endemic disease transfer
B. exposure to high concentration st ring operation may lead to occupational diseases of lung aspiration for a long time
C. the probability of long-term residents suffering from respiratory diseases in the surrounding area of the mine is greatly increased, because the long-term use of polluted groundwater
can cause other related diseases
land an important feature of the ecological impact of mine development and mining and dressing projects is land occupation. It includes permanent land occupation and temporary
land occupation
A. permanent land occupation, mining and instrial sites, gangue and infrastructure construction occupy a large amount of land, resulting in the change of land use types, which may occupy cultivated land or basic farmland, woodland, etc. As a result, the area of cultivated land is reced, the proction of agriculture and forestry is affected, and the economy, biomass and biodiversity of agriculture and forestry are lost
B. temporary land occupation, foundation clearing and land preparation will destroy vegetation, and soil and water loss will be caused by waste soil and slag
E. surface subsidence caused by mining, destruction of buildings, impact on agricultural proction and other facilities.

5. D open pit coal mining will damage the surface, cause soil erosion, and even lead to landslides, collapses and so on

7. Mining instry affects the environment

the impact of mining instry on the environment is mainly manifested in the following aspects:

ground fissures, ground collapses and debris flows inced by coal mining, surface water leakage, water level drop and water quality deterioration caused by mining, which also bring a lot of inconvenience to the proction and life of surrounding villagers

some mines mp waste ore and coal gangue at will, resulting in river and road blockage. Mining activities cause surface water pollution, air quality decline and so on, and destroy the ecological environment of the mining area and the living environment of residents.

8. Whether it is legal or illegal, mining is harmful.
