为了准确探明露天煤矿开采境界范围内已有的地下采空区,排除安全隐患,基于激光测距与GPS定位原理,采用C-ALS钻孔式三维激光扫描系统对平朔矿区露天煤矿境界范围内的地下采空区进行了全面探测。实践结果表明,该系统可以通过地表延伸至空区的钻孔迅速而安全的对采空区进行激光三维扫描,具有全自动、速度快、精度高、数据处理简便等特点。通过扫描,准确查明了已有采空区的尺寸参数,实现了采空区隐蔽工程的可视化,为露天煤矿地下采空区稳定性评价与治理提供了可靠的基础数据,对指导露天煤矿生产和维护作业人员及设备的安全具有十分重要的意义。

In order to accurately detect the existing underground gob in the boundary range of surface mine and to eliminate safety concerns,based on laser ranging a nd GPS positioning principle,the gob within the realm of Pinshuo surface mine had been fully detected by the cavity- autoscanning laser system. The results showed that th is system could san the gob quickly and safely through the drilling which from the surface to the empty area,which had the characteristics such as fully automatic,high spee d,high precision,simple data processing,etc. Through a comprehensive detection,the size parameters was implemented,which provided reliable basic data for underground gob stability evaluation and management of surface mine,and had great significance for guiding the surface mine production and protect the safety of the homework person nel and equipment.
