This research focuses on a steeply inclined coal seam fire zone in Xinjiang, proposing a novel 3D geological modeling and analysis approach that integrates multi-source data, including drilling and geothermal monitoring. Utilizing a software platform, a high-precision 3D model integrating topography, coal seams, fire zone boundaries, and the temperature field was constructed. This model enables the 3D visualization and precise delineation of the combustion extent and temperature distribution within the fire zone. Building upon this foundation, a new quantitative calculation method was developed based on the 3D block model. This method facilitates the classification of fire zone reserves, demarcation of remediation areas, and quantification of water injection volume, loess coverage volume, as well as excavation and leveling quantities. The results demonstrate that, compared to traditional two-dimensional methods, the proposed 3D quantitative analysis approach enhances the accuracy of remediation engineering quantity calculations by over 20%, significantly reducing project uncertainty. This research provides a robust technical framework for transitioning coal field fire zone remediation from "empirical judgment" to "3D precise quantification" in decision-making, holding significant theoretical importance and substantial engineering application value. |
