摘要
煤矿智能化建设对三维地质模型精度的需求日益增长。我国煤矿地质条件相对复杂,区域差异显著,目前尚缺乏适用于各类煤矿的三维地质建模方法。本研究基于交叉剖面建模方法,提出了针对超薄煤系地层地质建模交叉剖面布设的方法,并在内蒙古棋盘井煤矿进行了应用。通过交叉剖面布设,有效解决了显式建模岩层穿插问题,所构建的矿井模型分辨率达到5m精度,与控制点误差小于0.5m,实现了超薄煤系岩性地层建模的精细化要求。
The demand for precision in three-dimensional geological models in coal mine intelligent construction is increasing.China’s coal mine geological conditions are relatively complex and regionally diverse,yet there is currently a lack of a universally applicable method for three-dimensional geological modeling across various types of coal mines.This study,based on the cross-section modeling method,proposes a method for cross-section layout in geological modeling specifically tailored for ultra-thin coal seam formations.Practical application at the Qipanjing coal mine in Inner Mongolia demonstrated that the cross-section layout effectively resolves issues of intersecting rock layers in explicit modeling.Moreover,the constructed mine model achieved a resolution of 5m with control point errors less than 0.5m,meeting the requirements for precise modeling of lithological strata in ultra-thin coal seam formations.
