Abstract: Well based coalbed methane extraction is accompanied by groundwater pumping out from the coal seams. This determines the high need to estimate the influence of this subsoil use on natural water. Based on the analysis of natural conditions, the study found the key factors of groundwater flow formation in the prospective coalbed methane mining area. For the south province of the Kuznetsk coal basin, the minimum list was formed of specific hydrodynamic elements and their properties. This list is sufficient for parameters estimation during hydrogeological calculations and groundwater flow modeling for predicting of coalbed methane extraction influence on groundwater in the study region. For the convenience of practical use, the results are presented in table form. The ways of practical application and prospects to improve the proposed hydrodynamic scheme are discussed.
