Abstract
Mining industry, by underground coal exploitations allows the release of important methane quantities in the atmosphere.
Methane can be found stored both in coal deposits, as well as in sterile rocks from the proximity of coal beds. By carrying out the
degassing process in advance of the exploitation, there can be obtained at least three benefits simultaneously: a new source of
fuel for heating devices, methane emissions reduction and ventilation costs reduction.
With the help of computer, simulations of the coal bed degassing process can show in safe conditions the differences between the
situations that include this procedure and the situations in which the exploitation is performed without prior degassing of the coal
beds.
