摘　　要：结构面的发育程度、规模大小与组合形式是控制岩体稳定性的重要因素。露天矿动态开挖过程中形成的暴露空间可以为摄影测量提供良好的应用场景。根据岩体结构面的5级分类方案,使用无人机远景倾斜摄影测量手段获取II级与III级结构面,使用近景摄影测量手段获取IV级与V级结构面。将调查结果集成至SuperMap地理信息系统平台,远景摄影测量可以清晰、直观地反映乌山铜钼矿边坡已滑坡、潜在滑坡区域,获取断层、不整合面等地质构造;近景测量获取岩体质量、岩性分布等信息。远—近景摄影测量实现矿山边坡的三维可视化,并为边坡防护提供决策支持。The development degree,size and combination form of structural plane are important fac⁃tors to control the stability of rock mass.The exposure space formed during the dynamic excavation of open pit mines can provide a good application scenario for photogrammetry.According to the five-level classifica⁃tion scheme of rock mass structural planes,the UAV remote tilt photogrammetry method is used to obtain the II and III structural planes,and the close-range photogrammetry method is used to obtain the IV and V structural planes.The survey results are integrated into the SuperMap geographic information system plat⁃form.The prospective photogrammetry can clearly and intuitively reflect the landslide and potential land⁃slide areas of the slope of Wushan copper molybdenum mine,and obtain geological structures such as faults and unconformity surfaces.Close-range measurement to obtain rock mass quality,lithology distribu⁃tion and other information.Remote-closerange photogrammetry realizes three-dimensional visualization of mine slope and provides decision support for slope protection.
