The paper presents the problem of methane explosions prevention in the most hazardous mine section — working face, based on the preventive measures to exclude key factors of methane explosion. The measures of the methane explosions prevention in the working faces during the intensification of coal mining are determined. A method for the aggregated calculation of absolute methane emission in the working face at work of a shearer is proposed. An explosive concentration can occur at any time during cutting coal due to irregularity of methane emission and ventilation processes in the face, which makes the risk of explosion uncontrollable. Consequently, the effective preventive drainage of coal seams is primarily required for the intensification of coal mining. A series of new studies on intensity of methane emission will be required for per face output which is about 30,000 tons per day or more to create new regulatory documents.
