||Description of a mathematical method for assessing both the average concentration and the duration of peaks above the maximum admissible concentration of methane contained in the air emerging from mine workings. The method is based on the probability of methane outbursts and has been experimentally tested. The assessment of the above parameters is vital for the design of automatic safety systems for gassy coal mines.
