摘　　要：利用计算机技术进行矿体形态的模拟对指导矿山开采设计具有重要的意义。提出了一种基于移动立方体法的矿体绘制算法,研究了该算法的关键技术,即根据矿石品位寻找矿体的边界体元,在体元内构造三角面片拟合等值面。给出了求等值面的算法流程。采用该技术在某铁矿进行了实际的应用,取得了逼真的效果。最后,指出了该技术的进一步发展方向。The simulation of ore body using computer technology is of significance to the design of mining exploitation design. This paper presents a 3D rendering method of underground deposit based on a marching cubes algorithm, and studies the key rendering steps in which the verge voxel are found according to the ore grade and then triangle meshes are constructed to fit isosurfaces in verge voxels. The paper also outlines the algorithm for calculation isosurfaees. The technique was used to a certain Chinese iron mine, and a simulated true picture of the mineral deposit was depicted. At last some problems for further study are proposed.
