The coal is transported to thermal power plants, where it is grinded and transformed into dust. Coaldust is put into the boiler and transformed into thermal energy. High temperature is heating the water in tubes which are around the boiler and "transform" water into steam. Steam under big pressure is directed towards turbine blades producing mechanical energy . Mechanical energy from turbine moves generator which produces electric energy.
Coal dust suspended in air is explosive. Coal dust has far more surface area than chunks of coal per unit weight, and would be far more susceptible to spontaneous combustion
Coal Workers' Pneumoconiosis is caused by inhaling coal mine dust.
