The biggest coal mining operation on Earth - The Powder River Basin of Wyoming, United States.

 

The North Antelope Rochelle coal mine in the Powder River Basin of Wyoming, United States, was indeed one of the largest coal mines in the world. However, the status and rankings of coal mines can change over time due to various factors, including market demand, regulatory changes, and shifts in energy sources.

The Powder River Basin is known for its vast coal reserves, and several large coal mines operate in the region. North Antelope Rochelle, operated by Peabody Energy, has historically been one of the most significant coal producers in the basin.

It's worth noting that the coal industry has been facing challenges in recent years due to concerns about environmental impacts and the global shift toward cleaner and more sustainable energy sources. As a result, the coal mining sector has been undergoing changes, with some mines scaling down production or transitioning to other forms of energy or resource extraction.

For the most up-to-date information on the status and ranking of coal mines, especially in light of the evolving energy landscape, it is advisable to consult recent industry reports and news sources.
