三维激光探测技术在采空区测量中的应用与实践

Application Practice of 3D Laser Monitoring Technology in Finished Stope Survey

采空区严重影响矿山后续的开采规划,基于在大红山铜矿应用3D激光探测技术(CMS)采集矿山地下三维数据的实践,详细介绍了CMS技术在井下空区三维数据采集的方法、数据的预处理及应用实践。该技术采用无接触的测量方式,不但可以精确获取采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,还大大提高了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。

Mined area can severely affect the mine＇s follow-up production planning. Based on the practice of applying 3D laser monitoring technology （CMS） to collect the underground 3D data in Dahongshan Copper Mine, a detailed introduction is made of the 3D cavity data collection method, data pre-treatment and application practice of CMS technology. This technology adopts a contactless survey method. It can not only obtain the accurate spatial parameters of finished stopes such as length, area, volume, deformation of wall rock and roof and their change relation but also greatly improve the safety and efficiency of cavity data collection, providing the data for cavity safety evaluation and control and the design of ore-pillar extraction.
