摘要：

The technology of injection of concentrated carbon dioxide into the developed coal seam through horizontal boreholes drilled from the mine workings in order to increase its methane recovery is considered. A numerical model is developed and studied in the Comsol Multiphysics environment, which describes the process of injection of carbon dioxide into a rock mass. The results of numerical experiments on the investigation of the zone and parameters of injected carbon dioxide influence on equidistant degassing boreholes are presented.
