摘　　要：针对淮南市因长期煤炭资源开采,导致地表高程垂直下降、沉陷范围和沉陷深度不断扩大,引发地面沉陷、地裂缝、土地和植被的压占与破坏、地形地貌人文景观的破坏等问题,传统的观测手段无法满足地表沉陷预警、精确沉陷变化范围等需求,采用在传统观测手段的基础上结合高分辨率观测影像数据判读、无人机倾斜摄影测绘技术,获取沉陷区不同时期的相关数据,生成DOM、DSM、DEM模型。通过同类模型数据差值对比,判断地面的沉陷空间维度,并验证精度发现,观测方法真实可靠,具有可行性,达到沉陷监测的目的。Aiming at the problems such as due to long-term coal resource exploitation in Huainan City,which led to the vertical decline of surface elevation,the continuous expansion of subsidence range and depth,and cause ground subsidence,ground fissures,the occupation and destruction of land and vegetation,the destruction of terrain and landforms and human landscapes,etc.Traditional observation methods cannot meet the needs of surface subsidence early warning and accurate subsidence change range,and so on,on the basis of traditional observation methods,combined with high-resolution observation image data interpretation and unmanned aerial vehicle oblique photography surveying and mapping technology,relevant data of subsidence areas at different periods are obtained,and DOM,DSM,and DEM models are generated.Through the comparison of the data value differences of similar models,the spatial dimension of ground subsidence is judged,and the accuracy is verified.It is found that the observation method is true,reliable,and feasible,achieving the purpose of subsidence monitoring.
