利用三维空区探测系统(CMS)采集矿山地下三维数据,不但可以精确获取空区的空间几何参数,如长度、面积、体积、围岩及顶板的变形和变化关系,还可以大大提高空区数据采集的安全性和效率,为空区安全评价与治理以及矿柱回采设计提供数据。三维激光探测技术作为一项高新技术应用于矿山,其使用方法有一定的特殊性。为了提高扫描数据的精度及可靠性,在系统地介绍三维激光探测系统测量误差的基础上,详细分析CMS在空区扫描测量中影响最大的系统误差---侧滚向误差、仰俯向误差及定向误差,并提出相应的校正方法。
The use of three-dimensional space exploration system (CMS) to collect three-dimensional underground mine data can not only accurately obtain the space geometry parameters such as length, area, volume, deformation and variation of surrounding rock and roof, but also greatly improve the data Acquisition safety and efficiency, Vacant zone safety assessment and management, and pillar mining design data. Three-dimensional laser detection technology as a high-tech applications in mines, the use of a certain particularity. In order to improve the accuracy and reliability of the scanned data, based on systematically introducing the measurement error of the 3D laser detection system, the systematic errors that have the most influence on the CMS scanning in the empty space are analyzed in detail. The errors of roll roll, pitch error And orientation error, and put forward the corresponding correction method.
