基于三维激光扫描技术的矿山地质建模与应用

激光扫描技术(light detection and ranging technology)作为一门新兴的测绘技术, 目前已应用于诸多领域, 然而对于海量测站数据的拼接、大地坐标的定位等方面还存在一些不足.针对这2个问题, 提出分部式拼接方法以解决大数据量难处理的问题, 并利用罗德里格矩阵算法, 编程实现对地物的绝对坐标定位, 完成矿山的地质建模, 是对矿山地质建模新方法的探讨.通过与已知坐标数据的对比, 表明该方法的误差在矿山建模的允许值范围内, 具有较好的适用性.并以内蒙古白音诺尔铅锌矿地质建模为例, 可为覆盖区矿产综合预测提供3D矿床模型及预测要素空间形态特征等方面的参考. 

Mine Geological Modeling and Application Based on the Three-Dimensional Laser Scanner Technology

As a new mapping technology, light detection and ranging has been applied in many areas so far. However, for many aspects, such as the alignment of mass data, the location of geographic coordinates and so on, it still suffers some shortages. This paper, focusing on these two issues, puts forward the method of aligning by division parts to solve the problem of the large amounts of data, and to establish the geology modeling by using Rodrigo matrix algorithm to complete the absolute coordinates for the mine, which is a new method of the geological modeling. By comparison with the coordinate data, it indicates that the error of the method is within the allowed value range for mine modeling, with good applicability. Taking the modeling of Baiyinnuo'er Pb-Zn mine area for example, it can facilitate comprehensive mineral resources prediction for the coverage area, especially in perspectives of the 3D deposit modeling and prediction factor spatial characteristics.
