摘　　要：文章采用差分干涉测量短基线集时序分析(small baseline subset insar,SBAS-InSAR)技术,从平均沉降速度、累计沉降量及沉降面积三个方面出发,对西山煤田地区煤矿地面沉降进行检测,发现区域A1交城断裂带上的地面沉降主要是由煤矿开采和水资源开采引起,区域A2盆地和区域A3矿区累计沉降量变化轨迹均呈U形,且盆地的最大反弹幅度接近100 mm,矿区沉降后的反弹幅度则不足15 mm。因此建议选用长波长雷达,提升对矿区大梯度形变区域的检测能力。通过分析沉降面积,发现沉降面积缩减与累计沉降量反弹现象主要集中在断裂带南侧,研究成果为减少地质灾害损失提供了参考。This paper adopts Small Baseline Subset InSAR(SBAS-InSAR)technology to detect coal mine ground subsidence in Xishan coalfield area from three aspects:average subsidence velocity,cumulative subsidence and subsidence area.It is found that the ground subsidence on Jiaocheng Fault Zone of region A1 is mainly caused by coal mining and water resource exploitation,the cumulative subsidence trajectory of region A2 basin and region A3 mining area is U-shaped,the maximum rebound amplitude of the basin is close to 100 mm,and the rebound amplitude after subsidence in the mining area is less than 15 mm.Therefore,it is recommended to use longwavelength radar to improve the monitoring efficiency of large gradient deformation areas in mining areas.By analyzing the subsidence area,it is found that the reduction of subsidence area and the rebound of cumulative subsidence are mainly concentrated on the south side of the fault zone.The research results provide a reference for reducing the loss of geological disasters.
