摘　　要：煤矿区地表形变的动态监测是矿山环境恢复与综合治理的重要方面。为了解决目前传统测量技术手段无法大面积准确获取矿山地表形变信息的问题,文章介绍了一种时间序列分析方法——SBAS-INSAR技术,并选用克里金插值法对水准测量数据和SBAS-INSAR技术监测结果进行精度验证与评价。并在此基础上依托北斗卫星连续运行参考站监测系统总结地表形变规律,确定下沉系数,最终实现对城郊煤矿地表形变信息的精准监测和预测。研究结果表明:SBAS-INSAR技术监测地表形变成果精度达到±2.3 cm,具有较高的准确性和时效性,有效弥补了传统监测手段的不足。The monitoring of coal mine surface deformation is an important aspect of mine environmental restoration and comprehensive management.Aiming at the difficulties existing in the monitoring of surface deformation in coal mines,this paper indroduces a time series analysis method,SBAS-INSAR technology,and Kriging interpolation method is used to verify and evaluate the accuracy of leveling data and SBAS-INSAR monitoring results.Finally,the Beidou satellite continuous operation reference station monitoring system is used to predict and analyze the surface deformation trend of Chengjiao coal mines.The research results show that the result accuracy of SBAS-INSAR technology is ±2. 3 cm,with higher quality and timeliness,which can make up for the shortcomings of traditional monitoring methods.
