摘　　要：杨伙盘煤炭资源开采导致矿区范围内发生大面积地表沉降,严重影响当地人民的生产、生活。本文选用杨伙盘煤矿范围内Sentinel-1A数据,利用D-InSAR技术对矿区内2017年10月到2019年5月地面沉降范围与沉降幅度进行实时监测。监测结果显示杨伙盘矿区东部存在四个较大的沉降中心,最大形变量为-85 mm/y,累计形变量-128 mm,矿区内已发现的地表形变区仍在发生沉降作用。地质灾害的发生是一个缓慢积累到爆发的过程,建议后续继续开展研究区形变监测工作,特别是A点和B点区域应加强监测,以避免发生大规模地表形变。结果表明,D-InSAR技术能够有效获取矿区地表形变信息,可以为矿区沉降综合治理提供全面的形变信息,在灾害发生之前做出预警,提前做好防护措施,减少损失。The mining of coal resources in Yanghupan has caused a large area of land surface subsidence within the mining area,which has seriously affected the production and life of local people.In this paper,Sentinel-1A data within the scope of Yangpupan Coal mine were selected and D-InSAR technology was used to conduct real-time monitoring of the land subsidence range and amplitude in the mine from October 2017 to May 2019.The monitoring results show that there are four large subsidence centers in the eastern part of Yanghupan mining area,with the maximum shape variable of-85mm/y and the cumulative shape variable of-128 mm.Subsidence is still occurring in the surface deformation area found in the mining area.The occurrence of geological disasters is A process of slow accumulation to eruption.It is suggested to continue to carry out deformation monitoring in the study area,especially at point A and point B,so as to avoid large-scale surface deformation.The results show that the D-InSAR technology can effectively obtain the surface deformation information of mining area,and provide comprehensive deformation information for the comprehensive treatment of subsidence in mining area,so as to make early warning before the occurrence of disasters,take protective measures in advance and reduce losses.
