In the US alone, more than 100,000 coal miners were killed in accidents in the twentieth century, 90 percent of the fatalities occurring in the first half of the century. More than 3,200 died in 1907 alone.

During the American Revolution (), coal from this location was used in the manufacture of weapons for the American troops. Until this time, most coal used in the American colonies came from England or Nova Scotia. Wartime shortages and the needs of the munitions manufacturers spurred on small American coal mining operations.
Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

The largest and most long term effect of coal use is the release of carbon dioxide, a greenhouse gas that causes climate change and global warming. Coalfired power plants were the single largest contributor to the growth in global CO 2 emissions in 2018, 40% of the total fossil fuel emissions. Coal mining can emit methane, another greenhouse gas.
Over time, heat and pressure transformed the buried materials into peat and into various forms of coal. The geologist shows samples of low and highsulfur coal. Highsulfur coal contains a lot of pyrite, which is a mixture of sulfur, iron, and traces of other minerals. As long as it is underground, this mixture causes no environmental problems.
