摘　　要：因煤矿开采而引起的地表沉降对附近居民生活具有较大的影响,矿区地表沉降数据的获取对矿井生产布置至关重要。通过哨兵一号卫星获取覆盖平舒煤业15302工作面的30景影像,使用短基线集干涉测量技术对矿区地表沉降进行监测,获得了近2年的监测数据,计算了地表岩移主要参数,经计算可知:工作面走向方向的沉降量随时间不断增大,矿区整体平均沉降速率大于-30 mm/a,最大沉降速率为-108.87 mm/a,最大曲率为-0.1234 mm/m^(2),岩石移动角为78.2°。结果表明,该区域的地表倾斜与曲率均在允许值范围内,15302工作面的开采周边环境影响较小。The surface settlement caused by coal mining has a large impact on the life of nearby residents,and the acquisition of surface settlement data in the mine area is crucial for the production arrangement of the mine.Acquiring a 30-scene image covering the 15302 working face of Pingshu Coal Industry by Sentinel-1 satellite,monitoring the surface subsidence of the mine area using the short-baseline set interferometry technique,obtaining the monitoring data for the past 2 years,and calculating the main parameters of the surface rock movement,which can be calculated that:the amount of settlement in the strike direction of the working face increases with time,the overall average settlement rate of the mine area is more than-30 mm/a,the maximum settlement The average subsidence rate of the mine area is more than-30 mm/a,the maximum subsidence rate is-108.87 mm/a,the maximum curvature is-0.1234 mm/m/m,and the rock movement angle is 78.2°.The results show that the surface tilt and curvature in this area are within the permissible values,and the environmental impact of mining in the 15302 working face is relatively small.
