Examples of environmental pollution caused by mining
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

Such inspection results may have deviation, such inspection results are not rigorous
then, doctors generally emphasize that patients should not eat after 10 p.m. the day before the physical examination. They are allowed to eat before 10, and they are asked to eat. This is because physical examination is not allowed to keep the body in a state of starvation. p>
if you are fasting before physical examination, you may be in shock if you are in serious condition, and you may be in shock if you are not in shock.
