摘　　要：科学计算可视化是数字矿山的重要内容,也是近年来发展起来的一个新的研究方向。在矿业领域中,目前广泛采用三维线框模型来表达地质体的几何特征和赋存状态。根据地质体的不同类型和形成原因,建模方法也各不相同。在介绍了建模的基本原理之后,针对不对类型的地质实体,分别运用不规则三角网结构和线性八叉树码技术,结合工程实例,建立了某矿的地形表面模型、矿体线框模型和井巷工程模型。模型很好地反映了各地质体的实际形态,在实际生产中起到了重要的指导作用。Visualization in scientific computing is an important content in digital mine and is a new research orientation rising in recent years.In mining field,three-dimensional wireframe model is widely used presently to express the geometric characteristics and occurrence status of geological entities and the modeling methods are different depending on the types and formation causes of geological entities.After the description of the basic principles of modeling,the paper,in light of the geological entities of different types,the paper uses irregular triangulation structure and linear octree coding,in combination with a real case,to establish the landform surface model,orebody wireframe model and tunneling engineering model of the mine,which can well reflect the real form of the geological entities and play an important role in guiding the mining production.
