三维激光扫描技术在新疆黄土坡铜锌矿井下采空区实测中的应用

Application of 3D laser scanning technology in the underground goaf measurement of Xinjiang Huangtupo copper and zinc mine

为准确有效地分析新疆黄土坡铜锌矿采空区的稳定性,采用三维激光扫描技术对采空区的空间分布状态进行测量。与传统测量方法相比,三维激光扫面技术具有单色性、方向性、相干性和高亮度等优势。根据三维激光扫描技术的工作原理,结合新疆黄土坡铜锌矿井下空区测量,对其进行现场测试以及测量数据预处理,利用GEOMAGIC和DIMINE软件,点云构建新疆黄土坡铜锌矿采空区模型。结果表明:精确绘制出南北两个空区,且空区分别位于采场井下南部和北部。

In order to accurately and effectively analyze the stability of the goaf in Xinjiang Huangtupo copper and zinc mine,3D laser scanning technology was used to measure the spatial distribution of the goaf. Compared with the traditional measurement method,3D laser scanning technology had advantages of monochromaticity, directivity, coherence and high brightness. According to the working principle of 3D laser scanning technology, and combined with the measurement of underground goaf in Xinjiang Huangtupo copper and zinc mine, the field test and measurement data pretreatment were carried out, and GEOMAGIC and DIMINE software were used to point cloud construct the goaf model of Xinjiang Huangtupo copper and zinc mine. The results showed that two goafs were accurately mapped, and which were located in the south and north of the underground stope.
