Coal mining is still proceeding in some countries today, although EU countries have agreed to move to a carbon-neutral economy by 2050. Mine gases were developed during coalification. The quantity of gas inside the coal deposits depends on the: level of coalification, quantity of colliery tip and on conditions, which have contributed to the keeping of gas inside the coal deposits. Mine gases are endangering mining operation hence it is necessary to assure their dilution or extraction. We can use the extracted mine gas in different ways from supplies to the system of natural gas up to using it in different appliances. This article deals with the formation, acquisition and extraction of mine gas locally during mining operation. This technology increases the safety of the mining area. It contributes to the reduction of CH4 emissions and uses them for energy purposes.
