摘　　要：基于煤层精确的钻孔数据,采用狄洛尼三角剖分算法建立煤层上表面三角网(DTIN)模型。提出一种平面隐函数切割思想,实现平面和DTIN三维模型求交运算,生成离散切割交点,组成交点数据库。根据克里金插值技术研究采煤面范围内的钻孔点和切割交点,按建模精度要求生成虚拟钻孔和确定各点的煤层厚度信息,然后利用GTP体元地质体建模原理完成采煤面三维模型的构建。Based on the accurate drilling data of coal seam. Delaunay triangle subdivision algorithm is adopted to establish the seam surface triangulation （DTIN） model.Putting forward a kind of plane cutting ideas implicit function is used to achieve 3D model plane, DTIN intersection operations and generate many discrete cutting points. Based on Kriging interpolation technology research within the scope of the coal mining face of drilling and cutting points. According to the modeling accuracy,the virtual borehole and the thickness information of each point are generated, then using the GTP voxel made geological modeling principle of the coal mining face 3D model is build.
