Human beings have become an important factor in changing the appearance of the earth, even faster than all natural erosion sources. From space, we can clearly see that mining activities leave the most obvious "scar" on earth - open-pit mines. The destruction of the environment caused by economic interests has left endless troubles for the children and grandchildren.
Russian mill diamond mining pit
In Eastern Siberia, Russia, there is a diamond mining pit called Mir, which is 1200 meters in diameter and 525 meters deep. It takes two hours to open a truck from the bottom of the mine to the top. The advection of air flows into the pit, and the surface must bend down to the bottom of the pit. So above the diamond mine is a no-fly zone, because the downward swirling air in the hole can suck the helicopter into the hole and smash it. Its existence is like a monster, but its food is a plane!
Winter here is extremely cold, ground objects will freeze, but it is the annual output of 10 million carats of diamonds huge temptation to allow mining workers to overcome the extremely difficult environment, leaving a deep scar for the earth.
Wuda inner diamond open pit, Russia
Udachene Diamond Open-pit is located in Russia, near the Arctic Circle, in June 1955 discovered that the mining depth of more than 600 meters, is the world's third largest open-pit mining. The first and second largest mines are the Bingham Copper Mine in Utah (4 km in diameter, 970 meters deep) and the Churchikamata Copper Mine in northern Chile (4,300 meters long, 3,000 meters wide, 900 meters deep).
Bingham Copper Mine
Bingham copper mine is located in the United States. Since its mining, the total output of copper has exceeded 18 million tons, which is second to none in the world. The copper mine is 2.75 miles wide and 4,000 feet deep. Even if the two Empire State Buildings were stacked together, it could not reach the top of the mountain. By 2015, the Bingham copper mine will be 4,500 feet deep and will be able to drop an Empire State Building. It is the largest mining pit in the world today.
The Bingham copper mine began mining in 1904 and was also named historic site by the United States. The editor thinks that it is more appropriate to be named "human misdeeds".
Chili Kamata copper pit
Located 250km northeast of Antofagasta, Chile, Chile, the Cucchikamata copper mine is an open-pit mine with an altitude of 2,800m. It is the oldest copper mine in Chile. The depth of the mine is 850 meters. Although it is not the largest copper mine in the world, it is the most copper-producing mine in the world. It is also the second largest mining pit in the world.
Berkeley open pit, bout, Montana, USA
It was originally a copper mine, which was mined from 1955 to 1982, and later discovered gold and silver deposits. A well-designed drainage system makes the local water level very low, suitable for mining, but has caused great damage to the environment!
Today, the 1,780-foot Berkeley open pit is filled with 900-foot (270-meter) of sewage, mixed with metals and chemicals such as arsenic, cadmium, copper, zinc, pyrite, sulfuric acid. The acidity of the sewage is almost the same as that of the storage battery. The Berkeley strip mine is now listed by the U.S. federal government as a "superfund" pest disposal site because it could contaminate surrounding groundwater. Surprisingly, this place is actually a tourist attraction, with gift shops, and the tickets are two dollars.
Esmonte copper mine, Chile
Escandida Copper Mine, located in the Atacama Desert in northern Chile, began mining in 1990, with annual output ranking first in the world. In 2007, copper produced 1 million 500 thousand tons, worth about 10000000000 US dollars, accounting for nearly 1/10 of the world's copper output. The total number of workers in ESCOM is more than 6000.
UBA river gold deposit, California, USA
The mining activity of the Yuba River gold mine reached its peak in recent years. Workers used high-pressure water jets to dig in the upper Nevada Mountains, dredge from the Yuba River, search for gold and later gravel in the debris, resulting in this reddish-brown and gray hill, and a peculiar view of a valley filled with water between the hills. The Yuba River was eventually pumped into 685 million cubic feet of mining wastewater, raising water levels, spilling over the banks and flooding farmland.
This simple and crude mining method has brought incalculable damage to the local ecosystem. "Gold always shines" should be replaced by "Gold always digs up" in order to more in line with the law of human activities!
Peru copper Park
Located in the Andes of southern Peru, the Tokpala copper mine is 1.5 miles wide and 2,300 feet deep. The main ore of the mine is copper, but gold, silver and molybdenum have also been found.
Fry Potter copper mine, Indonesia
The Frey Potter mine, also known as the Glass Berg copper mine, is a large mine in the Indonesia's SUDI mountains. Here, copper was first discovered in 1936, and gold was in 1988. Today, fry Potter mine is one of the largest gold and copper deposits in the world. The open pit is 2.5 miles wide (about 4 kilometers) and there are large-scale underground mining activities in the area. You can see glaciers from photos. I wonder if human activities will cause these glaciers to melt away.
Mexico card Nani a mine
Kal Nani mine is located 25 miles (40 kilometers) south of the border between the United States and Sonora, Mexico. The corolla pit on the right side of the photo is 1.6 miles (2.5 kilometers) wide. It is the largest copper producer in the world and mining gold. These two metals are usually found together in the place where magma flows towards the superposed bedrock. Magma crystallizes there, and hot fluids circulate through it, into the cracks in the surrounding rocks, changing the nature of the rocks, producing copper-rich ores and gold.
Jordan phosphate ore
Phosphate mining is an important industry in Jordan. Jordan has rich phosphate deposits covering about 60% of the country's land. Phosphorus is a necessary mineral for all kinds of living things. Without it, food can not be produced. Some scientists worry that phosphorus, an important resource, will soon become inadequate, predicting that the world will enter the Peak Phosphorus within 30 years, when phosphorus production begins to decline. There is no artificial substitute for this mineral. In the picture, red represents plants, blue represents water, light yellow and black represent rocks and soil.
The mining industry is concentrated on the left side of the central part of the map, and the whole area is streaked with stripes. The whole picture is like a beautiful girl in a skirt who is walking but encounters a huge black obstacle on the way.
New union of copper ore, Arizona, Arizona
Around 1750, copper was originally taken from the south of the town of ako in this area. The opencast mine was extensively exploited in 1912. In 1983, due to the fall in copper prices, New Guinea's mine closed. The land on the right side of the mine is covered with mineral residues. The gray rectangle above is a polluted pond from which copper is extracted. The whole picture looks barren and bleak, giving a deep sense of powerlessness to the extent that the environment has been destroyed.
