储量计算工作量大,计算繁琐。传统方法是在二维图形的基础上,采用几何平均的方法计算完成。根据钻孔穿过矿体具有对称性,将同一矿体相邻剖面见矿钻孔进行连接,构建不规则三角网(TIN),将TIN中的三角形逐个沿钻孔向下扩展生成GTP,在此基础上以矿体表面为约束将矿体模型进行块段剖分,建立三维栅格数据模型,为矿体内部品位插值提供基础。该建模流程简单实用,对矿体储量计算具有很强的实用价值。
The calculation of reserves is heavy and the calculation is complicated. The traditional method is based on two-dimensional graphics, the use of geometric methods to complete the calculation. According to the symmetry of the borehole through the ore body, the mine borehole is connected with the adjacent section of the same orebody, an irregular triangular net (TIN) is constructed, the triangles in the TIN are extended one by one along the borehole to generate GTP, Based on this, the orebody model is divided into blocks by the constraint of the orebody surface, and the 3D raster data model is established, which provides the foundation for the internal grade interpolation. The modeling process is simple and practical, and has strong practical value for ore body reserves calculation.
