The potential of coalbed methane resource development and the safety of underground coal mining are directly determined by the coalbed gas content. In order to intuitively and accurately characterize the spatial distribution characteristics of coalbed gas content, guide the next project deployment and explore the idea of geology and engineering integration. The No. 3 coal seam in the west area of Sihe mine field was selected. Based on the data of the tested gas content and industrial analyzed coal samples of 28 wells and the coal seams layered data of 125 surface wells, firstly the multivariate regression mathematical model of gas content prediction was established. Then the three-dimensional attribute model of burial depth, moisture content, ash content, and fixed carbon content were established by geological modeling software, Finally the three-dimensional gas content model was built by numerical calculation in the geological modeling software, which was compared with the distribution characteristics of the average daily gas production within 10 years of gas well drainage. The results show that the mathematical prediction model is credible. The average gas content is 19.95 m3/t in the three-dimensional gas content model established by this method, and the distribution of gas content is obviously controlled by the burial depth. Compared with the conventional gas modeing, it is more consistent with the actual production capacity distribution characteristics. Contiguous high-yield wells with an average daily gas production of more than 4 500 m3/d are formed in high gas-contenting areas. The model is reliable and has guiding significance for the next well location deployment and numerical simulation to predict the distribution of remaining gas content.
