Posted by The Conversation on Monday, February 19, 2018 14:14:51In the run-up to the mining boom in the 1960s and 1970s, many of the world’s biggest coal mines in China were built on water-bearing rocks, making them toxic to humans.
These rock mines became the site of several environmental disasters, including one that resulted in the death of two young miners in 1972.
Today, more than a quarter of China’s coal mines are water-intensive, with some mines operating in water-rich areas, such as the Gobi Desert, or groundwater-poor areas, like the Yangtze River Delta.
In recent years, however, a growing number of China and US companies have begun to explore the idea of building new water-based coal mines.
The technology is being pioneered by two companies that will compete in a joint venture to develop the first mine in the United States.
According to the Associated Press, the Chinese government has granted the joint venture a license to mine coal from the United Nations’ Great Lakes Basin, which covers most of the state of Michigan.
The joint venture plans to mine 1.2 billion tonnes of coal, or 4.6 million tonnes of carbon dioxide per year, from Lake Huron.
That is more than the total amount of CO2 emissions from all coal-fired power plants worldwide, which is 3.6 billion tonnes.
The mining company is planning to operate the mine for 20 years, after which it plans to shut it down and rebuild the mine.
The mine is expected to employ 10,000 people and employ 2,500 people in construction and other work.
The Chinese government, which says it supports the development of coal mining in the country, has also made it clear that it will not permit foreign mines to operate in the Great Lakes.
However, it has not been the only country to pursue this technology.
In 2015, a group of French companies won the right to operate an 800-metre-long mine on the shores of Lake Huracán, in a bid to create jobs in the region.
The new mine would have a capacity of 6 million tonnes a year and would employ about 2,000 workers.
