摘要
针对传统地表监测方法中存在监测范围小、成本高、人力物力需求大等问题,使用2015-04-28~2016-03-05时间段内的13景RadarSAT-2数据,利用TCP-InSAR技术获得河北省邯郸市某矿区的地表沉降监测结果,并对沉降结果进行详细分析。研究结果表明,该研究区域内地表最大沉降速率为-106.21 mm/yr,最大沉降为-124.83 mm,且发生沉降区域与工作面位置相吻合。说明TCP-InSAR技术可作为一种切实可靠、方便快捷的手段实现对矿区地表进行长时间动态沉降监测,并用于分析矿区地表的开采沉陷规律,具有十分广阔的应用前景。
Traditional surface monitoring methods have problems such as small monitoring range,high cost,and large demand for manpower and material resources.Based on 13 RadarSAT-2 data from 2015-04-28 to 2016-03-05,we used TCP-InSAR technology to obtain the surface subsidence of a mining area in Handan City,Hebei Province,and conducted detailed analysis of the subsidence results.The research results show that the maximum surface subsidence rate in the study area is-106.21 mm/yr,the maximum subsidence is-124.83 mm,and the subsidence area coincides with the working face position.It shows that TCP-InSAR technology can be used as a practical,reliable,convenient and fast means to achieve long-term dynamic mining area surface subsidence monitoring,and analyze the mining area surface subsidence pattern.Its application prospect is very broad.
