摘　　要：针对传统测绘方法在采矿区沉降监测中的不足,为及时而准确地获取到采矿区的沉降信息,利用小基线集(small baselines subset InSAR,SBAS-InSAR)技术对因挖掘煤矿造成的采煤区上方及周边进行持续沉降监测。以某煤矿获取的高分辨率商用雷达卫星RADARSAT-2的多期数据,计算该区域一年的沉降量及沉降速率,并与往年数据进行对比分析,研究煤炭开采造成的地面沉降及其变化规律。结果表明,该技术在采矿区沉降监测中满足监测要求,其结果的精度可以达到毫米级。In order to overcome the shortcomings of traditional surveying and mapping methods and obtain the information on subsidence in mining areas timely and accurately,the SBAS-InSAR technology was used to continuously monitor the subsidence above and around the coal-mining area.Based on the multi-period data collected by the high-resolution commercial radar satellite RADARSAT-2 from a coal mine,the amount and rate of subsidence in the area in one year were calculated,and compared with the data of previous years to analyze the land subsidence caused by coal mining and the law of subsidence.As shown by the results,this technology can meet the requirements for monitoring subsidence in mining areas,giving millimeter-level accuracy.
