    目前矿山生态修复多采用全站仪或者GPS-RTK测量,具有强度大、周期长、成本高的缺点,尤其是废弃露天矿山存在的滑坡、坍塌等问题给测绘人员带来安全隐患,且传统的测绘手段均为二维的结果,地形地貌、地质灾害信息不直观,给生态修复方案的设计带来不便。为了满足露天矿山生态修复实际需求,利用无人机倾斜摄影测量技术开展矿山生态修复。在勘查测绘阶段,利用无人机倾斜摄影测量建立实景三维模型,基于实景三维模型进行信息采集,生成3D数字产品;在方案设计阶段,结合地质灾害信息、实景三维模型、测绘3D数字产品进行生态修复设计、工程量统计、投资预算,并建立生态修复效果模型;在施工管理阶段,利用无人机倾斜摄影测量技术对工程的施工进度、工程量、施工效果进行动态跟踪、实时监测、效果对比。研究结果表明无人机倾斜摄影测量技术可以实现:保障技术人员安全,节约人力、财力等成本投入,使勘查测绘更加高效;矿山环境信息更直观、生动、形象,有利于生态修复方案的制定,使方案设计更加科学;动态监测、掌握施工进度、监督施工与设计的符合度,使得管理施工更加全面;分项治理工程量统计、预算金额计算、工程量量化,使矿山生态修复更加精准;留存矿山历史档案,对宣传开展矿山生态修复发挥带动作用。

     




  • Abstract
    At present,the methods of total station or GPS-RTK are widely used in mine ecological restoration,which have problems of high intensity,long period and high cost. Especially for abandoned open-pit mines with disasters such as landslide and collapse,which bring serious security risks to surveyors. At the same time, tradit ional surveying and mapping production can not directly and truly show the topography and geomorphology of abandoned open-pit mines for its plane 2-dimension,whic h brings inconvenience to the design of ecological restoration scheme. In order to meet the needs of ecological restoration in open-pit mines,the application of unmanne d aerial vehicle( UAV) tilt photogrammetry technology was proposed to carry out mine ecological restoration. Firstly,in stage of preparation work, basic information,geolo gical data and mining data of mines are collected and airspace is applied. Secondly,in stage of exploration and mapping,the UAV tilt photography is carried out to establ ish the 3 D model of the real scene. During mentioned process,quality control measures were used to improve accuracy of the real scene 3 D model. The 3 D products are achieved by above real scene 3 D model. Then,in the design stage,combined with geological hazard information,3 D model,3 D digital products,ecological restoratio n design,engineering quantity statistics,investment budget are carried out,and the effect model is established to demonstrate the scheme. The design scheme is used fo r the construction after assessment from different perspectives such as regulation effect,investment amount,construction period ,industrial development,etc. Finally,in sta ge of construction management,the UAV tilt photography technology is used to obtain the real 3 D model for dynamic monitoring and effect comparison which can achie ve digital and quantitative management. The UAV tilt photogrammetry technology has been applied in the ecological restoration of abandoned open-pit mines in Hebei P rovince. All data results meet the requirements of relevant regulations. The results show that: this technology can make survey and mapping more efficient,scheme desi gn more intuitive,management and construction more comprehensive,mine ecological restoration more accurate,which provide strong technical support for mine ecologi cal restoration. At the same time,the preservation of the historical archives of the mine is of great significance for promoting ecological restoration and playing a leading
