ABSTRACT

Methane emissions released into the atmosphere during coal mining, exerts a double
environmental impact, namely they participate to the ozone layer depletion process and,
simultaneously, they have a significant contribution to the enforcement of the
greenhouse effect. On the other hand, this methane can be used by the mining operators,
as main or ancillary fuel resource for energetic purposes. Until now, in Romania an
overall energetic potential study was not systematically carried out, regarding the hard
coal basin Valea Jiului. The paper presents, based on several systematic measurement
campaign’s results, the estimate for the methane volumes released both through the
main ventilation shafts and the central degasification plants, from the collieries
operating in this basin. There are also synthesized and outlined the results obtained by
means of comparative analysis on coal mine methane valorization alternatives and the
feasibility of environmental impact mitigation by Valea Jiului methane valorization.
