Abstract: To predict gas content distribution in No.14 mining area of Zhaojiazhai Coal Mine, combined with the exploration seismic data, based on intercept and gradient properties, seismic attributes of P-wave impedance, shear impedance, polarization parameters, density and pseudo-Poisson's ratio are obtained. There is a correlation between seismic attributes and coalbed gas, high gas content of coal seam generally forms a strong AVO anomaly, low gas content of coal seam AVO anomaly is weak. By AVO inversion technique, a correlation between the different seismic attributes and coal seam gas content is established, and Zhaojiazhai coal seam gas distribution content of No.14 mining area is obtained. The study shows that the prediction error between predicted gas content and measured gas content at the coal seam of borehole is low, which indicates that the prediction of coal-bed gas content by the AVO inversion technique is a valid approach.
