Abstract: The new methodical developments according to the forecast of methane-abundance dynamics of the high-productive panel at working flat and inclined seams with a complete collapse of the roof, considering specific mining-and-geological and technological conditions of conducting mining operations are necessary for ensuring effective airing of extraction sites. The main aim of the study: to determine the mining-and-technological parameters of the modern panel, changing dynamics of implementation of gas capacity of the massif and intensifying aero-gas exchange on border a face working – the developed space and to execute the forecast of the expected gas content of excavations. Adaptability of the forecast is provided with accomplishment of estimates based on mining-and-geological data on properties of the massif in the specific mountain block taking into account their variability, use of new knowledge of natural forms and conditions of methane in coal layer and dynamics of methane emission in a zone of conducting clearing works. The proposed prediction method allows closer looks at the reaction of the gas components are working on the formation to change the situation in the geomechanical rock mass. The results: increase of reliability of technological solutions and management of methane-abundance panel, including specification of the requirements for the methods and schemes of ventilation.

Key words: coalseam panel face working methane-abundance forecast ventilation
