摘要: 本文通过列举3个工程案例说明InSAR技术在开采沉陷中的应用,首先将InSAR技术与三等水准测量进行对比,明确了InSAR技术在矿区形变监测领域的精度和可靠性;然后针对淮南某关停矿井,应用SBAS-InSAR技术获取了研究区的时序形变信息,并对照采空区稳定性评价指标,得出了该矿区地表已稳定的结论;最后以某村庄部分房屋建筑出现不同程度的损伤为研究背景,在常规方法获取开采影响范围的基础上,进一步利用SBAS技术和8景Sentinel-1A数据,明确了村庄地表已处于稳定状态。结果表明,InSAR形变监测技术能够为开采沉陷损害溯源及沉陷稳定性判定提供有力的科学依据。

Abstract: This paper illustrates the application of InSAR technology in mining subsidence by listing three engineering cases. Firstly, the InSAR technology is compared with the third-class leveling to clarify the accuracy and reliability of InSAR technology in the field of mining deformation monitoring. Secondly, SBAS-InSAR technology is used in a closed mine in Huainan to obtain the time series deformation information, and the solution results are compared with the goaf stability evaluation index, concluding that the surface of the mining area is stable.Finally, based on the research background of some houses and buildings in a village with different degrees of damage, and on the basis of conventional methods to obtain the scope of mining impact, the SBAS technology and 8 Sentinel-1A data are further used to confirm that the village surface has been in a stable state. The results show that InSAR deformation monitoring technology can provide a powerful scientific basis for mining subsidence damage tracing and settlement stability judgment.

Key words: mining subsidence, InSAR, stability evaluation, damage identification of mining subsidence mining, temporal deformation
