How far underground are coal mines?
Coal that occurs at depths of 55 to 90 m (180 to 300 ft) are usually deep mined, but in some cases surface mining techniques can be used. For example, some western U.S. coal that occur at depths in excess of 60 m (200 ft) are mined by the open pit methods, due to thickness of the seam 20–25 metres (60–90 feet).

Why are mines so hot?
Deep underground mines are “hot” work sites because of the heat from the rock itself. Ground water flowing through hot rock formations becomes hot and adds to the air temperature. Activities like drilling, blasting, and welding add to the heat load put on miners, on the surface and underground.
Why is coal mining bad?
Along with adding to greenhouse gas pollution, burning coal emits toxic and carcinogenic substances into our air, water and land, severely affecting the health of miners, workers and surrounding communities.
