From11930 s to 1970 s, many serious pollution incidents occurred in countries all over the world, which caused people to die of impatient poisoning, and the consequences were very serious. Therefore, people's awareness and attention to the environmental hazards caused by natural accidents became increasingly prominent. Taking Banshan Gold Mine in Fuxin City as an example, this paper makes a risk assessment of the potential danger of the gold mine.

The second paragraph is translated as follows

Cyanide wastewater in groundwater was identified first, and then analyzed from two aspects: material danger and potential danger of construction projects. It was screened out that the risk of gold mine pollution was the most credible accident. Finally, the method of combining data frequency analysis and event tree analysis is used to quantitatively analyze the credible maximum accident. Because of the cyanide-containing wastewater studied in this paper, the rainy season has no wrong impact on the environment, only considering the impact of the rainy season on the leakage of groundwater leaching water. However, cyanide is a highly toxic substance after all. At present, there are many uncertain factors in the prediction of cyanide content in the pit bottom of open pit mining. Therefore, it is very necessary to reduce tailings storage and cover the soil immediately after tailings storage reaches its service life.

Some articles are long. I hope to read them carefully and help you.
