【摘要】 矿区开采沉陷会给地表建筑及人员安全带来巨大威胁，监测矿区时序沉降并为地表建筑安全提供指导意见具有重大意义。本文基于SBAS-InSAR技术开展了M矿区近5年的时序沉降监测，确定了M矿区的沉降区域及年平均沉降速率，并对重点沉降区域展开时序分析。另结合哨兵数据强度图像及GF-1号光学影像解译矿区地表建筑群信息，联合InSAR形变场对主要建筑区的安全性进行分析。结果表示，矿区以三矿和二矿的地表沉降最为严重，而一矿的沉降相对较小。矿井A区、B区都有沉降继续加深、影响范围继续扩大的趋势。矿区地表建筑群中，A1南部进入矿区的部分、A2以及B3建筑群安全性较差，沉降速率达30～60 mm/a，后续需进行现场勘探，做好建筑安全防护及安全预防工作。而A3、A4、B2建筑群，沉降速率为0～30 mm/a，值得后期关注。B1及C～G区建筑群沉降速率为0～20 mm/a，安全性相对较好。更多还原

【Abstract】 The mining subsidence in the mining area will bring great threats to the safety of surface buildings and personnel. It is of great significance to monitor the time series subsidence of the mining area and provide guidance for the safety of surface buildings. Based on SBAS-InSAR technology,this paper carried out the time series subsidence monitoring of M mining area in the past five years,determined the subsidence area and annual average subsidence rate of M mining area,and carried out time series analysis on key subsidence areas. In addition,combined with the sentinel data intensity image and GF-1 optical image to interpret the information of the surface buildings in the mining area,combined with the InSAR deformation field to analyze the safety of the main building areas. The results show that the surface subsidence of the third and second mines in the mining area is the most serious,while the subsidence of the first mine is relatively small. Both areas A and B of the mine have a tendency to continue to deepen and expand the scope of influence. Among the surface building complexes in the mining area,the part of the southern part of A1 entering the mining area,and the building complexes A2 and B3 are less safe,with a settlement rate of 30～60mm/a. Follow-up site exploration is required to do a good job in building safety protection and safety precautions. The settlement rate of A3,A4,and B2 buildings is 0～30mm/a,which is worth paying attention to later. The settlement rate of the B1 building group and the building groups in C～G areas is 0～20mm/a,and their safety is relatively good.更多还原
