You teachers should be middle school teachers?!! Coal mining can cause mountain cracks, collapses, landslides and collapses, increase the water conductivity of the soil, cause a large loss of soil moisture and nutrients, reduce soil fertility, and pose a threat to the growth of crops and trees. Coal mining is also very damaging to water systems.
In the process of coal mining and production, the goaf scope continues to expand, forming the peak of water inflow in the whole mining process, and the surface water is rapidly transformed into groundwater, so that the groundwater body has changed from the original horizontal movement to vertical movement, destroying the shallow water source and seriously affecting the water use of industry and agriculture. Surface runoff has decreased significantly, and the groundwater level has dropped sharply, resulting in a series of problems such as cracking of housing buildings, land subsidence and water accumulation, river embankment sinking, reduced flood discharge capacity, and spring water interruption.
Case in point: In 1994, the famous Jin Ancestral Hall Nanlao Spring was cut off due to over-mining of coal. There are two main ways to pollute surface water from coal mining:
Pit drainage and gangue leaching directly pollute surface water flows. The pit water is not only mixed with a large amount of coal dust and harmful elements, but also seriously polluted by the underground rotten pit wood, oil, etc., and directly pollutes the river flow after being discharged from the surface. Gangue contains a large number of soluble ions, especially heavy metal ions, which are easily migrated to water and cause pollution under the erosion and leaching of surface water and groundwater.

This reason is one of the important causes of soil erosion in the Loess Plateau (rich in coal resources) in China.
Mining destroys local surface vegetation, reducing soil and water conservation capacity and exacerbating soil erosion.
At the same time, due to the destruction of a large number of native vegetation, it will lead to the degradation of forests and grasslands, and the development of desertification.
It should be noted that in humid and sub-humid areas, soil erosion tends to be the main manifestation, while in arid and semi-arid areas it is often mainly desertification.

If there is open mining, it will, even if it is a hole mining, it may also cause disasters such as ground subsidence.

Agree with the upstairs insight!
Coal mining can certainly cause soil erosion.
But in my personal opinion, the upstairs should not be sarcastic about LZ...

Summary. Kiss <>
I am glad to answer for you, coal mining land subsidence and soil erosion, compensation for six to ten times the average annual output value in the three years before the expropriation, Article 47 of the Land Management Law: If the land is expropriated, compensation shall be given according to the original use of the expropriated land. The compensation fee for the expropriation of cultivated land includes land compensation fee, resettlement subsidy fee, and compensation fee for ground attachments and seedlings.
The land compensation fee for the expropriated cultivated land shall be 6 to 10 times the average annual output value of the cultivated land in the three years preceding the expropriation.
Coal mining land subsidence and soil erosion, how to compensate.

In principle, the scope of compensation should include: the price payable by the mining right holder for the overlying resource reserves under the current market conditions (except for the group of people who take the overlying resources without compensation); Direct losses such as exploration files or state investment, investment in existing mining facilities, and relocation of corresponding facilities for the share of overlying mineral resources.
Coal mining land cracks, the soil can not be cultivated without water, how to solve it?
The two parties can settle the quarrel through negotiation, or they can request the villagers' committee and the township (town) people to mediate. If the parties are unwilling to negotiate or transfer the bank to the world, or if the negotiation or mediation fails, they may arbitrate or directly file a lawsuit with the people's court.

In the course of mineral resource development, soil erosion was caused by the destruction of surface vegetation, indicating that natural resources have the integral characteristics of connection
Therefore, c
The total amount of soil erosion reduction is calculated by subtracting the amount of soil erosion after the measures taken during the construction period of the main project. Specifically, it includes the following three aspects: >>>More
In recent years, the area of forest land has been increasing, but soil erosion is still serious in some places due to problems such as vegetation species, planting techniques or management. As a soil and water conservation worker, the author has conducted surveys in some towns and villages, and found that in many places, the phenomenon of emphasizing planting and neglecting management is widespread in afforestation work, and to a certain extent, man-made soil erosion has occurred. >>>More

Tinnitus is a common symptom of ear diseases, patients feel that there is sound in the ear, the loudness is different, and the high-pitched tinnitus will make people annoyed and affect sleep and work. Its appearance may be intermittent or persistent, and sometimes ear chickens may be the first symptom and accompanying symptoms of some diseases, and the cause of tinnitus is not yet clear in medicine. >>>More
