为动态分析老采空区上方地表残余变形规律,本文以淮南矿区新庄孜矿新淮工厂为例,综合运用D-InSAR遥感解译反演与地表移动变形监测两种方法分析其残余变形规律,并以遥感解译数据与实测数据为基础资料,采用GM(1,1)模型进行地表残余变形规律的动态预测。D-InSAR存档数据反演结果显示2009年1月—2011年12月期间地表最大下沉量为100 mm,最大下沉速率为2.5 mm/d;地表移动变形监测结果显示2012年1月—2013年12月期间地表最大下沉量为55 mm,最大下沉速率为0.45 mm/d;GM(1,1)模型预测结果显示地表监测点下沉速度小于1.67 mm/d,地表处于残余衰退阶段;同时模型相关系数R2>0.95,预测结果和曲线拟合精度可靠。研究成果可为煤矿老采空区上方建筑地基残余变形监测工作提供参考。 In order to dynamically analyze the residual deformation of the ground surface above the old goaf, this paper takes Xinhuaizhuang Xinhuai Plant in Huainan Mining Area as an example, analyzes the residual deformation law by D-InSAR remote sensing interpretation and surface deformation monitoring, The GM (1,1) model was used to predict the residual deformation of the ground surface based on the data from remote sensing interpretation and the measured data. The inversion results of D-InSAR archival data show that the maximum surface subsidence is 100 mm and the maximum sinking rate is 2.5 mm / d during the period from January 2009 to December 2011. The monitoring results of surface deformation show that from January 2012 to January 2013 The maximum surface subsidence was 55 mm and the maximum subsidence rate was 0.45 mm / d during December. The GM (1,1) model predicts that the surface subsidence velocity is less than 1.67 mm / d and the surface is in the stage of residual decay ; While the model correlation coefficient R2> 0.95, the prediction results and curve fitting accuracy is reliable. The research results can provide a reference for the monitoring of the residual deformation of the foundations above the old goaf in coal mines.
