The Dangers of Coal Mining
14.05.2019In addition to this, coal mining sites also tend to be very noisy which means that most miners suffer from some degree of hearing loss over the course of their career. Instability Many coal mines are held in place by supports that are built as the mines are excavated which means that they lack structural support.

What are hazards associated with carriage of coal?
Coal may have any or all of the following hazards: Spontaneous heating: Coal is very liable to spontaneus heating. Freshly mixed coal absorbs oxygen, forming peroxides which break up into carbon monoxide and carbon dioxide. This is an exothermic reaction and the heat produced causes further oxidation and more heat.
