The quality of mining in juxiangyou
During the period of western development in the United States, gold panning has become a hot instry, and countless people with American dream go to the west to panning for gold, which means that they have made a lot of money, but in the end, those who panned for gold didn't make a lot of money, and those who sold jeans made a lot of money

ID is the abbreviation of identity, which means identification number. It's a serial number, also known as account number, which is a code and the abbreviation of instrial design. It is equivalent to a kind of "ID card". In a specific thing, the ID number is generally unchanged. As for what to use to identify the thing, it is determined by the rules made by the designer himself. Generally speaking, this rule has certain subjectivity in design according to the specific use environment, such as: "employee number", "ID number", "computer web site" and so on. For computers, there are mainly two operation modes, logic operation and arithmetic operation. Logic operation is related to the ID function of numbers. ID is very common in life. For example, you paste the proct model and proction number on similar things to distinguish them. This can also be called ID. ID is very common in life.

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

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
