A method for determination of sources of methane liberation from an undermined massif includes determination of limiting distance () by normal between the seam being developed and superimposed seams wherein methane liberation from the last one is practically equal to zero, with determination of number of all the coal and rock seams comprising methane gas distance from which to the seam being developed is smaller compared to the set limit one. In experimental way one determines the distance from the mounting working to the breakage faceat instant of maximum gas liberation to wells of underground degassing with following calculation of limit distance
