Chování a vlastnosti metanu v systému voda-hornina-plyn v reálných podmínkách zatopené dílčí pánve OKR.

Abstract

Within the mine gases, when methane is usually only dangerous component in the OKR, its general effect while ascending to the surface to the environment and to public safety are very specific. In the Ostrava-Karvina district, mine gases remained in coal seams and accompanying rock kept in a certain volume. The main component of mine gases here is methane. With regards to the transfer of the methane during geological proces, it is possible to make just a rough estimation of the primary content of methane in the coal seams of the given coal basin. The measurements content of methane according this disertation were performed depending on the depth in mine waters and atmospheric pressure in the water pits. They were carried out in Jeremenko water pit and Sophia water pit in Ostrava-Karvina district. The achieved results are presented in tables and graphs.
