摘要

通过3GSM三维岩体不接触测量技术,对夏甸金矿-615分层水平54902采场进行矿岩体裂隙和结构面数字摄影测量,获取一系列真实反映岩体宏观结构的图像,从中提取节理裂隙和结构面的空间分布信息。在此基础上,利用东北大学自主研发的不稳块体快速识别和分析系统Geo SMA-3D,进行某测点的不稳块体搜索。最终将表征结构面、关键块体形态的数据实体化后集成到虚拟场景之中,实现矿岩体特征的快速识别、确认及真三维展示的功能。
        Through 3GSM three dimensional rock mass non-contact measuring technology, the author carries out digital photogrammetry on ore rock fracture and structural surface in 615 hierarchical level 54902 stope of Xiadian Gold Mine, obtains the image of a series of reflecting rock macro structure to get the spatial distribution information of joint fractures and structure surface.On the basis of this, using the instable block fast recognition and analysis system(Geo SMA-3D), the author searches instable block in the measuring points, eventually makes characterization of structure surface, key block data materialized integrated into the virtual scene to achieve rock mass characteristics rapid identification and confirm 3D display function.
