Poyang sand mine is a large-scale sand mining operation in Poyang Lake, China. It is located in the eastern province of Jiangxi and is the largest sand mine in the world. The mine has been operating since the early 2000s and has extracted billions of tons of sand from the lake.

The Poyang sand mine is not actually a single mine, but rather a network of sand mining operations that have been operating in Poyang Lake since the early 2000s. The lake is the largest freshwater lake in China, and it is estimated that sand mining operations have extracted billions of tons of sand from the lake over the past two decades.

It is difficult to say how old the Poyang sand mine is. The sand mining operations have been going on for over 20 years, but it is possible that there was some sand mining activity in the lake before that. However, there is no clear evidence to support this claim.

The Poyang sand mine is the largest sand mine in the world by volume. However, there are other sand mines that are larger in terms of surface area. For example, the Sua Pan sand mine in Botswana is larger than Poyang Lake in terms of surface area, but it has not extracted as much sand.
