摘　　要：随着地下煤炭资源开采,地表沉降使得农田耕地与建筑物受损,开展采煤地表沉降规律分析具有重要的意义。对淮南某矿某首采面设置了地表移动观测站,通过采前全面观测、日常观测以及采后全面观测,分析获取了该工作面走向观测线与倾斜观测线的下沉曲线,同时利用Sufer8.0对各期地表测量数据进行处理,生成了该工作面各期下沉盆地三维可视化图,提取了各期走向与倾向主断面上下沉影响距离,计算得到了各期地表下沉盆地面积,并对该首采面各期地表下沉盆地形态与下沉影响面积动态演变规律进行了分析。研究结果可为同类型矿区工作面科学开采及采后的环境综合治理提供一定的技术支持。With the mining of underground coal,the farmland and buildings are damaged due to surface subsidence.The surface movement observation station is set for the working face in Huainan mining area,and the Sufer8.0 is used to process the ground surveying data,and the 3D visualization map of subsidence basin of each phase is generated.The subsidence influence distance of the main section of the strike and dip in each phase is obtained,and the surface subsidence influence area is calculated.The subsidence basin and the dynamic evolution law of subsidence area is analyzed.The study can provide some technical support for scientific mining and comprehensive environmental treatment.
