| 摘 要： | 为解决传统的人工野外矿山地质环境调查易受交通、地形影响，且劳动强度大、效率低、成本高等问题，将无人机摄影测量技术应用在矿山地质环境调查中。以长春市净月东升采石场为研究区，利用RTK（实时动态差分技术）获取地面控制点坐标，采用大疆精灵4无人机进行航空摄影，在Pix4Dmapper建立的研究区三维模型上经量测、解译等，提取研究区内矿坑面积、边坡方位、长度、高度、体积和表面积以及滑坡、崩塌堆积体和断层等矿山地质环境相关的几何信息，制作了研究区地形图、DOM（数字正射影像）和DSM（数字表面模型），同时解译了边坡大量随机结构面迹线和产状信息。结果表明，基于无人机摄影测量技术的矿山地质环境调查可以快速获取矿山地质环境信息，获取的结构面倾向、倾角误差分别在5°和4°以内，可满足矿山地质环境调查精度要求。

| Abstract: | Traditional field survey of mine geological environment is easily affected by traffic and terrain,and labor intensity, the working efficiency is low, and the cost is high. In this paper, the application of unmanned aerial vehicle (UAV) photogrammetry technology in mine geological environment survey is studied. By taking Changchun Jingyue Dongsheng quarry as the study area, the ground control point coordinates were determined by using the RTK(real-time kinematic), and the geometric information related to the mining environment in the study area was obtained by using DJI Phantom 4 UAV for aerial photography, such as slope orientation, length, height, volume, surface area, landslides, collapsed deposits, and faults. After measurement and interpretation, the 3D model of the study area was established by using Pix4Dmapper, topographic maps, DOM,and DSM of the study area were made,meanwhile,a lot of trace and orientation information of random discontinuities were interpreted. The results show that the mine geological environment survey based on UAV photogrammetry technology can quickly obtain the information of mine geological environment, and the discontinuity dip and dip angle errors obtained are within 5° and 4° respectively, which meet the precision requirement of mine geological environment survey. |
