Chandgana Tal (Mongolian: Чандгана Тал, rigid-steel steppe) is a coal mine in the Mörön sum (district) of Khentii Province in eastern Mongolia.
The mine has an annual production capacity of 3 million tonnes of coal.
Changana Tal mine is in the bag #5 of Mörön sum.
Chandgana Tal coal was first discovered by Russian surface reconnaissance in 1941 and subsequently explored in detail in 1962–1963.
In 1967, a small mine was opened to supply heating coal for local consumption (Öndörkhaan city) and the mine has operated more-or-less continuously since, producing up to 20,000 tonnes of coal per year.
