| 摘 要： | 针对我国金属矿同山存在的大量采窄区安全隐患，在国内首次提出了以3D激光探测技术为基础的空区探测新方法。根据在大厂矿区的探测试验及相关应用实例表明，该技术提高了采夺区探洲的准确性和精度，可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等，为空区安伞评价与治理以及矿山回采设计等提供了相对可靠的参考依据。

| Abstract: | Considering the hidden danger in the finished stopes in underground metal mines in China, a new cavity survey method based on 3D laser scanning technology is proposed for the first time in China. The results of the survey experiment in Daehang Mine District, Guangxi and other related applications indicated that this method could enhance the survey accuracy and precision, by which can be obtained precise geometrical parameters of the emptied stope such as length, area, volume, deformation of roof and wall rock and so on. It provides a relatively reliable basis for the safety evaluation and control of emptied stopes and the design of mine stopping. |
