真三维地质体建模技术及其在煤田地质勘探的应用

A Real 3D Geological Modeling and Its Application in Coalfield Geological Exploration

在煤田地质勘探中,面对复杂多变的地质体,利用三维地质建模技术将其实际形态真实的反映出来,可以有效的指导勘探工程布置、见矿点预测等。三维地质实体模型除描述物体的轮廓外,还应具备地质体体积和表面积计算、任意方位剖面切割、地质构造形态展示、地层稳定性评价功能。三维地质实体模型建立方法主要有剖面线法、合并法、相连段法。以宁夏洪涝池勘探区地质实体模型建立为例,其主要模型包括:钻孔模型,地形表面模型,煤系地层与断层等地质体三维空间模型等。在最终生成的地质模型中,可以清晰反映出Q、E、煤系地层、断层面、煤层底板等高线等地质体。

Real 3D geological solid modeling is of great importance to engineering design and construction as well as information management, analysis and decision making. Especially in coalfield geological exploration, in the face of complexity and levity of geological bodies, using 3D Geological solid modeling technology will lay out its true form, and will help exploration project disposal, forecast a mine information. The author presented a method to model 3D geological bodies. Finally, the 3D geological solid model for a coalfield geological exploration was established by using its practical data and was used in the work successfully.
