露天矿采空区激光三维探测应用研究

Application research of 3D laser detection in Open-pit Mine goaf

阐述了C-ALS钻孔式三维激光扫描系统的工作原理、操作步骤、数据处理方式,并以国内某露天煤矿采空区激光三维探测项目为背景,举例说明三维激光扫描技术在露天矿安全生产中的作用。实践表明,激光三维探测方法是目前比较有效的采空区探测方法,通过扫描可以准确实现隐蔽采空区的可视化,为露天矿采空区治理提供了可靠的基础数据。

This article describes the working principle, operation steps, data processing way of C-ALS drilling 3D laser scanning system,and illustrates the effect of 3D laser scanning technology in safety production based on domestic open-pit coal mine goaf3 D laser detection project. Practice shows that 3D laser detection method is more effective method of goaf detection,which can accurately realize the visualization of hidden goaf by scanning,and provide the reliable data for the open-pit mine goaf treatment.
