In post-mining areas appearance of uncontrolled mining gas exhalations can be observed. Methane migrating through the strata, together with soil air may create explosive mixtures. Occurrences of mining gases are caused due to discontinuation of water pumping process in abandoned mines and fast rising and restoration of water table. However, it?s not obvious, that all hydrocarbons in soil pores come from abandoned hard coal mines. Often in soil pores mixtures of microbial and thermogenic gases are observed. For ide...
