生成块体模型是矿山三维储量计算中首先要解决的问题。针对传统方法效率低下及精度差的问题,提出了一种基于BSP树结构的三维块体模型快速填充算法。该算法适合于复杂矿体及地形约束下大数量级块体的生成,已成功应用于多个矿山的三维储量计算中,结果表明了该算法具有高效、准确、适用性强等特点。

Building block model is the key problem that should be solved in mine 3D calculation of reserves. Due to such problems as low-efficiency and low-precision using the traditional method, this paper raises the rapidly filled arithmetic of 3D block model by BSP tree structure. This algorithm is adopted to build the magnitude of blocks model under constraint of the complicated ore body and terrain, and it has been successfully used in 3D calculation of reserves in some mine, meanwhile showing the arithmetic is efficient, precise and operable.
