Gas Migration in the Aspect of Safety in the Areas of Mines Selected for Closure

One of the main hazards occurring in post-mining areas is uncontrolled migration gases to surface, which may pose a serious threat life and health. These are mainly methane carbon dioxide, smaller amounts ethane higher hydrocarbons, oxide, hydrogen sulfide, radon. Methane migrating into lower levels buildings, garages, cable ducts, sewage systems reaching concentrations above 5% cause an explosion hazard. The concentration dioxide over 4% also represents life. Moreover, methane, emitted atmosphere, constitute considerable source greenhouse gases. could be utilized, yet it necessary develop effective capture purification methods with first step determination being its routes. paper presents application numerical modelling use TOUGHv2.0 software, enabled simulation multiphase flow, applying adsorption diffusion phenomena. results gas were compared outcomes geological tests, obtained satisfying. It was observed that both investigation computer simulations proper tools for phenomenon identification hazard on constituting basis development further application.
