多源数据下老采空区上方地表残余变形规律分析

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。

Analysis of Old Goaf Surface Residual Deformation Regulation Based on Multi-source Data

For analyzing the regulation of surface residual deformation above old goaf, the surface residual deformation regulation above Xinhuai factory by remote sensing interpretation method and surface residual deformation monitoring is studied, and the dynamic residual deformation regulation with historical archive data and real-time data monitoring based on GM(1,1) model is predicted. According to the inversion of historical archive data. The result shows that the maximum sinkage is 100 mm from January 2009 to December 2011;the maximum residual sinkage is 55 mm from January 2012 to December 2013; the residual subsidence of surface monitoring point is stable. The research result could provide reference for the building foundation residual deformation monitoring work above old goaf.
