Why Coal Mining Is Bad? Coal mining releases toxic materials into the soil and water. Bad mining can start coal fires which can burn for decades - releasing "fly ash" and smoke filled with greenhouse gases and toxic chemicals. It releases coal mine methane which is 20 times more powerful than carbon dioxide.

What Causes Coal Fires? Coal has the unique ability to self-heat, which over time can lead to spontaneous combustion. Self-heating is the result of increased temperature and a chemical reaction between an oxidant (Oxygen). When this happens, you have a lump of chemically activated carbon. Hot spots can develop even with tiny amounts of oxidation.

Coal mining destroys natural habitats, not only through deforestation and mountaintop removal, but also by contaminating the surrounding land and waterways. This, in turn, can harm or kill plants and animals and disrupt entire ecosystems. Coal mining can also cause coal-seam fires, when outcrops or underground coal seams catch fire.

One well known source of fires is mining breaking into a high pressure cavity of methane gas which on release can generate a spark of static electricity to ignite the gas and start a coal explosion and fire. The same gas static is well known in ships and care has to be taken to ensure no such static sparking can occur.
