The invention, which belongs to the field of geological exploration, relates to a geological tracing and reconstruction method of gas. The method comprises three parts: three-dimensional reconstruction of a coal-forming environment is carried out to restore a coal-forming environment and a three-dimensional space mode; and basic conditions of gas reservoir forming, coal primary structure, and reservoir physical and mechanical properties are cognized; geological structure evolution and historical foming, reservoir, extinguishing processes of the gas are reconstructed, the structure evolution ofa coal measure strata is combined with the concomitant methane gas reservoir rule to realize inversion of the time and space changes of the coal seam burying and the historical foming, reservoir, extinguishing processes of the gas, and a dynamic gas geological model is established; and numerical simulation and similar simulation experiments are carried out on geological relics feature quantitative reconstruction of gas,
