Mountaintop removal mining (MTR), also known as mountaintop mining (MTM), is a form of surface mining at the summit or summit ridge of a mountain.

In the 1800s, making a ton of steel required a greater weight of coal than iron ore.

In communist times (1945–1989) one of the most important and largest mines was 1 Maja Coal Mine. In 2020, coal played a significant role in Poland's energy mix, making up 69.5% of the nation's energy production and 68.5% of its electricity generation. It accounted for 40.2% of the Total Energy Supply (TES).
