They emit a considerable amount of methane to the ventilation air. The emission depends on many but mostly known factors. The article presents the research results on changes in the methane concentration along the longwall excavations and longwall. The distributions were obtained based on a measurement experiment at the ZG Brzeszcze mine in Poland. The author’s research aimed to experimentally determine the concentration of methane as a function of the length of excavation for the longwall excavations and longwall. As a result, methane concentration trends along the excavations were obtained. The conclusions show the pros and cons of the method used, and it allows to set the right direction in the development of measurement systems and sensors.}, type={Article}, title={Measurements of the Methane Concentration Along the Longwall Excavations and Longwall}, URL={http://ochroma.man.poznan.pl/Content/122707/PDF/Archiwum-67-1-12-Ostrogorski.pdf}, doi={10.24425/ams.2022.140861}, keywords={measurements of the methane concentration, section measurements, Y system, individual methane meters, inspection and monitoring, mining, data fusion}, }
