Based on the well logging data and on-site coring results of the No.3 coal seam in Yuwu-Gucheng Block,based on the characterization of GSI value,a well logging interpretation model for the GSI characterization value of coal body structure is established through the correlation analysis between the GSI characterization value and well logging parameters,thus to achieve continuous and accurate representation of coal body structure through well logging parameters.The result shows that the GSI value of coal body structure calculated from well logging data in Yuwu Block is consistent with the result of on-site coring,indicating that this prediction method is suitable for the discrimination of coal body structure in this block.
