摘　　要：矿区开采往往会带来地面沉降、地面塌陷等多种相关的地质环境问题,依靠传统的地面调查或仪器监测去收集矿区的地表形变信息效率不高且成本相对昂贵,InSAR技术的出现为此类有地表形变的地质灾害提供了更高效、更具性价比的监测方式。基于Sentinel-1A数据,利用SBAS-InSAR技术对松宜矿区进行地表形变监测,获取2017-03-12—2019-10-28地表形变结果,划定四个沉降区,即无沉降区、轻微沉降区、较大沉降区和严重沉降区,并着重分析6个沉降现象较为严重的子矿区逐年地表沉降速率及其变化趋势。结果表明,通过SBAS-InSAR技术解译的形变活跃范围与地面调查获取的成果有着较好的一致性,该技术可以为复杂山区中矿区地质灾害防治工作提供重点靶区,同时也为矿区地面沉降的监测预警研究提供新的思路。Mining often brings various related geological and environmental problems such as ground subsidence and ground collapse in mining areas.Relying on traditional ground surveys or instrument monitoring to collect information on surface deformations in mining areas is not efficient and relatively expensive.The emergence of InSAR technology provides a more efficient and cost-effective method for monitoring such geological disaster with surface deformation.Based on the Sentinel-1A data,the SBAS-InSAR technology was used to monitor the surface deformation of the Songyi mining area,and the results of the surface deformation from March 12,2017 to October 28,2019 were obtained,and no settlement area,slight settlement area,large settlement area,severe settlement area were delineated.The year-by-year surface subsidence rate and its changing trend of the six sub-mining areas with more serious subsidence phenomena are analyzed.The results show that the active range of deformation obtained through ground surveys is in good agreement with the interpretation results of SBAS-InSAR technology.This technology can provide key target areas for subsequent geological disaster prevention and control work,and it also provides new ideas for monitoring and early warning research on ground subsidence in mining areas in the future.
