摘　　要：为了实现矿区开采沉陷损害的高效可靠鉴定,以山西东坡煤矿开采井田为研究对象,利用合成孔径雷达干涉测量(InSAR)技术监测分析了该区域矿区开采所引起的地表形变,同时基于概率积分模型预计了该矿区开采移动变形情况,随后利用边界角确定了开采边界,结合实地调查最终确定该井田开采是否会对矿区附近某村庄产生损害影响。结果表明:分析矿区在2007年1月至2019年4月期间InSAR形变监测结果以及预计的地表移动变形发现,该村庄始终处于由边界角确定的开采损害边界以外,同时结合实地调查发现建构筑物未有采动损害迹象。In order to efficiently and reliably identify mining subsidence damage of the mining area in Dongpo Coal Mine,Shanxi Province,synthetic aperture radar interferometry(InSAR)technology was used to monitor and analyze the mining-induced surface deformation.At the same time,the probability integral model was used to predict the surface movement and deformation.Then,the mining boundary was determined using the boundary angle,and field investigation was carried out to determine whether the mining-induced surface deformation would damage to a nearby village.According to the analysis of InSAR deformation monitoring results and predicted surface movement deformation in the mining area from January 2007 to April 2019,the village was always outside the mining damage boundary determined by the boundary angle.And no signs of mining damage to the buildings was found in the field investigation.
