摘要 为提高黄金矿山采场验收测量精度与工作效率,以山东某黄金矿为例,应用三维激光扫描技术代替传统测量方法对该矿地下采场体积进行测量和计算。根据三维激光扫描测量模式,分析了激光扫描数据处理流程,构建了测量误差分析模型,研究了测量误差、采样间隔对采场体积计算的影响以及三维激光扫描数据格式转换与数据共享机制,探讨了三维激光扫描数据在SURPAC软件中的应用以及不同等高线间距、抽稀间距对采场体积计算精度的影响。研究表明:利用三维激光扫描技术能够快速精确获取采场三维空间数据,构建采场三维精细模型;为进一步提高采场体积的计算精度,可将三维激光扫描数据采样间隔设置为50~200 mm,等高线间距应小于0.5 m,抽稀间距不宜大于1.5 m。

Abstract: In order to improve the accuracy and efficiency of stope acceptance measurement in gold mine,taking the under stope of a gold mine in shandong Province as the study example,the underground volume of the mine is measured and calculated by adopting 3D laser scanning method instead of traditional measurement method.According to the measurement mode of 3D laser scanning,the data processing flow is discussed,the measurement error analysis method is established,the influence of the error of 3D laser scanning and sampling interval to stope volume calculation is studied,data format conversion and data sharing mechanism are analyzed,besides that,the application of 3D laser scanning data and the influence of different contour interval and thin interval to the calculation accuracy of stope volume are analyzed.The study results show that 3D spatial data can be obtained by using 3D laser scanning technique,and some related model with high precision can be established,besides that,in order to improve the calculation accuracy of stope volume,the reasonable sampling interval of 3D laser scanning data is 50~200 mm,the contour interval should be less than 0.5 m and the thin interval should not be greater than 1.5 m.
