摘　　要：针对传统采煤区沉陷监测存在的工作量大、点观测、范围小、地面标志易被破坏等问题,本文以凉水井煤矿431301工作面为研究对象,采用大疆M210RTK专业无人机在工作面开采过程中进行多期航测,经过影像空三计算、三维模型生成、特征数据采集和数据挖掘分析,构建地表沉陷模型。基于沉陷模型进行走向、倾向下沉量计算,并进行沉陷边界角计算、工作面整体下沉分析。结果表明:无人机倾斜摄影测量应用于采煤区沉陷监测,能够满足确定下沉范围、下沉量、不同下沉量区域分布等监测要求,该技术在采煤区沉陷监测具有一定适用性。In view of the problems existing in the traditional mining area subsidence monitoring,such as large workload,point observation,small scope,and easy destruction of ground signs,this paper takes the 431301 working face of Liangshuijing coal mine as the research object,and uses the Dajiang M210RTK professional UAV to carry out multi-phase aerial photogrammetry in the mining process of the working face,and constructs the surface subsidence model through aerial triangulation,3D model generation,feature data collection and data mining analysis.Based on the subsidence model,the subsidence of strike and dip is calculated,and the subsidence boundary angle is calculated,and the overall subsidence of working face is analyzed.The results show that the application of UAV oblique photogrammetry in subsidence monitoring of coal mining area can meet the monitoring requirements of determining the subsidence range,subsidence,regional distribution of different subsidence,and the conclusion shows that the technology has certain applicability in the subsidence monitoring of coal mining area.
