摘　　要：为进一步探究煤矿地表形变的更多细节内容,以双鸭山矿区煤田地煤矿开采造成的地表形变问题为研究案例,应用合成孔径雷达干涉测量(InSAR)技术展开研究,基于InSAR的煤矿地表形变监测原始图像,通过对原始图像进行解译和细节处理得到研究区域沉降量分布、沉降量与开采距离之间的关系,以及沉降量与时间的关系等,结合现场实测方法对本次基于InSAR的煤矿地表形变监测的准确性进行对比检验,检验结果显示,针对剖线上的58个节点的数据相关性分析而言,当显著水平取0.05时,相关系数最小值为0.256;当显著水平取0.01时,相关系数最小值为0.330。通过查表对比后可知,剖线水准测量值与InSAR测量值具有较好的相关性。证明水准测量值和InSAR测量值也无显著差异。若以水准测量结果代表地面沉降的真实情况,则本次InSAR监测值可反映出研究区内整体沉降情况,证明本次基于InSAR的煤矿地表形变监测方法较具准确性,具有一定的应用价值。To further explore more details of the surface deformation of coal mines,taking the surface deformation problem caused by coalfield in Shuangyashan mining area as a research case,synthetic aperture radar interferometry(InSAR)technology was applied to conduct research.Based on InSAR,the original image of coal mine surface deformation monitoring was obtained.By interpreting and processing the original image,the distribution of settlement in the study area,the relationship between settlement and mining distance,and the relationship between settlement and time were obtained.Combined with on-site measurement methods,the accuracy of InSAR based coal mine surface deformation monitoring was compared and tested.The results showed that test results for the data correlation analysis of the 58 nodes on the section line,when the significant level was taken as 0.05,the minimum correlation coefficient was 0.256;when the significant level was taken as 0.01,the minimum correlation coefficient was 0.330.After checking the table and comparison,there is a good correlation between the profile leveling measurement values and InSAR measurement values.Prove that there was no significant difference between the leveling measurement values and InSAR measurement values.If the leveling results represent the real situation of ground settlement,the In SAR monitoring value can reflect the overall settlement in the study area.Therefore,it is proved that the coal surface deformation monitoring method based on InSAR is accurate and has certain application value.
