Provided is a method for fracture communication, passage processing and underground gasification of an underground carbon-containing organic mineral reservoir, where a mixture of CO 2 and O 2 is used as a medium for a fracture communication step, a passage processing step and/or a gasification step. The method uses the mixture of CO 2 and O 2 to extract and utilize the energy in the underground carbon-containing organic mineral reservoir, greatly increases energy utilization efficiency compared with conventional utilization schemes, and, compared with conventional underground gasification technologies, increases the calorific value of a combustible gas, increases and adjusts effective gas compositions, suppresses CO 2 generation and reduces raw material gas production costs, while at the same time implements the capturing of CO 2 and utilization of the same as a resource.
