摘要
鉴于常村煤矿地区地表形变监测具有特殊和复杂性,进一步验证SBAS-InSAR技术在常村煤矿地区地表形变监测效果。采用短基线集干涉测量(SBAS-InSAR)技术,对常村煤矿地区地表形变进行监测,选取2015年11月—2022年4月的Sentinel-1A升轨SAR影像数据,共56景影像,通过对Sentinel-1A SLC影像进行裁剪,裁剪后监测区域面积为123 km2。结果显示,常村煤矿外扩1 000 m范围内平均地表形变速率在-58.95~10.54 mm/a;渑池分输清管站外扩500 m区域内平均地表形变速率在-18.93~10.01 mm/a。由此可见,研究区内存在一个较大的沉降漏斗(河南大有能源股份有限公司常村煤矿西南部区域)和较小的沉降漏斗(常村煤矿中东部区域);煤矿所在的天池镇周边存在着较大的沉降,主要是矿产资源开采引起的沉降。长期进行矿区监测对常村煤矿地区生态重建、地质灾害评估和防治具有重要意义。
In view of the special and complexity of surface deformation monitoring in Changcun Mine area,the surface deformation monitoring effect of SBAS-InSAR technology in Changcun Coal Mine area was further verified.Short baseline set interferometry(SBAS-InSAR)technology was used to monitor the surface deformation in Changcun Coal Mine area.The Sentinel-1A ascending rail SAR image data from November 2015 to April 2022 were selected,with a total of 56 images.By tailoring Sentinel-1 ASLC images,the monitoring area was 123 km 2 after tailoring.The results show that the average surface deformation rate within 1000 m extension range of Changcun Coal Mine is between-58.95 mm/a and 10.54 mm/a;the average surface deformation rate within 500 m extension range of Mianchi pipe station is between-18.93 mm/a and 10.01 mm/a.It can be seen that there is a large settlement funnel(the southwest area of Changcun Coal Mine of Henan Dayou Energy Co.,Ltd.)and the smaller settlement funnel(central eastern area of Changcun Coal Mine);there is a large settlement around Tianchi Town where the coal mine is located,mainly due to mineral resources mining.Long-term monitoring of the mining area is of great significance to the ecological reconstruction,geological disaster assessment and prevention and control in Changcun Coal Mine area.
