ABSTRACT
Coal Mine Methane (CMM) could be valuable source of energy for electricity and heat production. On the other hand, methane migration from gobs, through overburden strata, to the atmosphere, has non-negligible influence on global warming effect. Accidents caused by uncontrolled methane migration, from abandonment coal mines, are also commonly known. In this article worldwide and Polish experiences of CMM migration modeling are shown. Short review of CMM utilization are also presented. Authors discussed several models of gases migration and accumulation in overburden strata in the area of "1 Maja" and "Niwka-Modrzejów" abandoned hard coal mines. Petro-physical parameters used to numerical model building are shown. Results of gases migration modeling are collected and pointed out. Model of methane production from "Moszczenica" hard coal mine is also considered. In addition, some American experiences of coal mine methane exploitation from gobs are also discussed within this article.
