The coal production in low-permeability gas-bearing coal seams brings the problems with advance methane recovery from coal array to reduce gas emission in a goaf. Technology of advance methane recovery from low-permeability coal array aimed at improving safety in coal mines. This stimulates the development of new technology methods improving the properties and state of the environment. Given the great heterogeneity of the coal properties of the array and the complexity of the exposure active, effective effort is possible only through a series of sequential engineering impacts. Technology of underground coal array involves solution of the problem of effective management of gassing using vibration and reservoir wells. In this regard, the proposed technological scheme of methane recovery is designed with consideration of the conditions of occurrence of the layer and the desired level of reduction of natural recoil of methane, To solve this problem, the proposed technology managed wave action, which provides an intensive extraction of methane gas from the low-permeability coal array at the stage of preparation of the reservoir to the hollow.
