Abstract. A method for determining methane content in the panels considers the methane content as total amount of gas emitted from the undermining seam, contiguous coal seams, enclosing rocks and loose lumps transported on the site and from some areas of goafs. Methane discharge into the panel face is calculated with taking into account different production rates and geological characteristics of outburst-prone coal seam.  Potential methane discharge into the air space of the face is considered.

It is shown that "The Guidelines on Calculation of Ventilation ..." being currently in force do not fully comply with modern requirements for calculating dependence between total coal output and acceptable level of methane content in the panels with taking into account high production of existing mining-and-hauling machines.

Key words: methods of determining methane соntent excavation site, the methane production rate, the level of coal mining.
