摘要: 煤层对比和三维地质建模是煤矿工程优化与安全高效开采的重要基础,煤层对比为地质建模提供数据支撑,地质建模则为多源地质信息融合与可视化分析提供了有效途径。 目的 为摸清新疆大南湖七号煤矿主采煤层发育特征,实现多源地质信息融合可视化表达, 方法 基于地质勘探与采掘揭露资料,采用标志层、煤层间距、煤质参数、测井曲线及地震剖面多方法协同开展煤层精细对比研究。结合钻孔数据、煤层对比成果和矿井工程设计资料,采用深探地学建模软件构建煤矿地层-构造-采掘巷道三维地质模型,进一步将多源地质属性信息进行三维可视化融合。 结果 结果表明:研究区主采煤层自上而下划分为 3,5,6,7,10 煤层,各煤层特征差异显著,其中 3,7,10 煤发育稳定,为全区可采煤层。通过煤层精细对比,厘定了各煤层间的复杂层组关系,解决了煤层对比空间关联性难题,为三维地质建模提供了数据基础。构建的三维地质模型准确刻画了主采煤层空间展布特征和构造发育规律,直观展示了巷道工程布设与采掘空间位置关系,实现了矿井多源地质信息的融合可视化表达,突破了传统二维剖面或平面解译的局限性。 结论 研究结果可为矿井智能化建设与安全开采提供地质决策依据。

Abstract: Coal seam correlation and 3D geological modeling are essential foundations for optimizing engineering design and ensuring safe mining in coal mines. Coal seam correlation provides data support for geological modeling, while geological modeling offers an effective approach for the integration and visualizationof multi-source geological information. Objectives To clarify the characteristics of the coal seams in the Dananhu No. 7 Coal Mine in Xinjiang and achieve the visualization of multi-source geological information integration, we conducted a detailed investigation based on geological exploration and mining exposure data. Methods By integrating marker beds, seam spacing, coal quality parameters, logging curves and seismic profiles, a comprehensive approach was adopted for precise coal seam correlation. Using borehole data,coal seam correlation results, and mine engineering design data, the Deep Exploration Geoscience Modeling software was employed to construct a 3D geological model of the strata, structures and excavation roadways, further enabling the 3D visualization and integration of multi-source geological attributes. Results The results show that the main coal seams in the study area are divided into No. 3, No. 5, No. 6, No. 7 and No. 10, with significant differences in their characteristics. Among them, No. 3, No. 7 and No. 10 coal seams are stable and mineable across the study area. Through detailed coal seam correlation, the complex interlayer relationships were clarified, resolving the challenges of spatial correlation in coal seam comparison and providing a robust data foundation for 3D geological modeling. The constructed 3D geological model accurately depicts the spatial distribution of coal seams and structural patterns, visually presenting the spatial relationships between roadway engineering layouts and mining activities. This model achieves the
integrated visualization of multi-source geological information, overcoming the limitations of traditional 2D cross-section or planar interpretations. Conclusions This research provides geological support for the intelligent construction and safe mining in coal mines.
