东周窑井田多尺度三维地质建模

Multi-scale 3D geological modeling of Dongzhouyao Coal Mine

构建了东周窑井田地质信息库;利用DepthInsight三维建模软件将东周窑井田作为研究对象,采用断层交切处理、“小层建模”、三角网格剖分、截断网格剖分等技术构建了东周窑井田多尺度三维地质模型。井田尺度模型以三维的形式概括性展示井田内的构造,并在此基础上采用克里金算法进行插值计算,预测出山4#、5#煤层中火成岩的分布;地震勘探区尺度模型揭示了此区域煤层形态以及构造特征,在此模型的基础上对8402、8403等8个规划工作面进行模拟,实现了地下构造可视化;工作面尺度模型是精度最高的模型,以8100工作面为例探索了工作面高精度三维地质建模及动态更新的方法。

The geological information database of Dongzhouyao Mine Field was built. Taking Dongzhouyao Coal Mine as the research object by using DepthInsight 3D modeling software, and complicated structure, three different scales of 3D geological models were constructed by using techniques such as “fault intersection treatment”, “small layer modeling”, “Delaunay triangulation grid”and “truncated mesh generation”. The mine field-scale model generally displays the structure in the minefield in three-dimensional form. Based on it, the Kriging algorithm is used for interpolation calculation to predict the distribution of igneous in Shan 4#and 5#coal seams;the scale model of seismic exploration area reveals the coal seam morphology and structural characteristics in this area. Based on this model, 8 planned working faces such as 8402 and 8403 are simulated to realize the visualization of underground structure;the working face scale model is the most accurate model. Taking 8100 face as an example,the method of high-precision 3D geological modeling and dynamic updating of working face is explored.
