Abstract
Methane emitted by the hard coal mines in operation in the Jiu Valley coalfield is under study in order to find out the most suitable solutions that increase occupational health and safety and at last, but not in the least, to capitalize the power generating potential of it. From the point of view of occupational safety, methane displays the highest risk because it can give birth to an explosive mixture with the air and the coal dust. Methane discharges into the outer atmosphere have a negative impact, increasing the greenhouse effect, with serious consequences over the parameters of the climate. This paper focuses on the use of mine gas in three important stages: solutions for the use of methane discharged by central degassing stations for power generating purposes; development of the network for the drainage of gases and increasing the volume of recovered methane; solutions for the use of CH4 from the general ventilation.

The extractive industry, in particular, pollutes the air, water and soil through its activities
This paper presents certain aspects related to pollution with the methane discharged by the main ventilation stations at the hard coal mines in the Jiu Valley
Due to a large variation of forms, thickness, inclines and extension of hard coal beds, as well to the physical and mechanical features of the surrounding rocks, there are different mining methods[1]: - The mining for small and average coal bed thickness; - Mining for thick coal beds At the end of 2019, the gross production from the mines in the Jiu Valley, was about less than 500.00 million tons
Summary
The extractive industry, in particular, pollutes the air, water and soil through its activities. This paper presents certain aspects related to pollution with the methane discharged by the main ventilation stations at the hard coal mines in the Jiu Valley. The Hunedoara Energy Complex extracts coal from the Jiu Valley through 4 mining units. The amount of methane discharged unit the air by these stations can reach hundreds of thousand of cubic meters/day at a concentration under 1% vol Methane represents an important factor in the global heating process; it has a green house effect 21 times higher than carbon dioxide which can adversely influence the world clime. This paper presents the method used to discharge methane into the surrounding atmosphere, the amounts and concentrations, methane capitalization and proposals for future uses of methane through unconventional means
