    This paper is based on the analysis of long-term desorption tests with the use of the USBM - a method applied to document coalbed methane in Poland since the mid 1990s. Tests were performed on coal samples representing five grain classes and samples were taken from six different sites in the technological process of coal mining, processing and post-exploitation processing on the surface. The tests were carried out with the use of variance analysis method with a single (one factor) classification on the example of the Hard Coal Mine „Budryk”.
