Asia’s Largest Open-Pit Mines Outside China Are Mainly Coal Mines

Coal mining and the generation of energy from coal are being pushed back further and further in the Western world, especially in the United States and the EU. This is mainly due to the high CO2 emissions caused by energy generation from coal. In Asia, the issue of CO2 emissions is also being addressed, but the countries here intend to rely even more on coal-fired energy in the coming years since coal is a reliable source of energy.

This is matched by the fact that most Asian open-pit mines outside China are primarily coal mines. Which are the largest open-pit mines in Asia?.[1]
