    The coal seam methane pressure seems to be a main parameter which is necessary for evaluating the probability of occurrence of some hazards in hard coal mine industry. An in situ measurement of this parametere is very difficult, so it was necessary to find an indirect method of such measurements. The laboratory method is generally based on the shape of the isotherm of the total methane content in the examined coal. The coal for the laboratory tests should be collected from a place in a coal bed where the methane content is well known. This paper presents an application of the worked out method to the estimation of the coal seam methane pressure level in the coal mine »Krupiński«.
