摘要/Abstract

摘要： 实现露天矿山重点区域、关键环节重大安全风险的识别监测是当前国家矿山安全监管的重要目标。围绕露天矿山尾矿坝体、排土场边坡安全识别监测的实际需求,以山西岚县—娄烦铁矿区作为研究区,利用共计35景 Sentinel-1A SAR数据组成的92个小基线干涉对,基于融合分布式散射体的DS-InSAR技术,验证了该技术应用于区域性露天矿山地表形变监测的有效性、适用性,并对该区域内尾矿坝体、排土场边坡地表形变特征进行分析研究。监测结果表明:DS-InSAR技术有效识别到研究区内3座尾矿坝体、3处排土场边坡地表形变,考虑到这些尾矿坝、排土场处于运行阶段,地表形变以固结下沉和自密实作用变形为主;同SBAS-InSAR技术相比,DS-InSAR技术经相位优化重构后目标点相干性明显提升,相干点数量增长至6.5倍,且地表形变相关系数为0.81,为尾矿坝体、排土场边坡地表形变隐患识别及其稳定性评估、地表形变机理研究提供技术和数据支撑。研究表明,袁家村铁矿与尖山铁矿迫切需要加强对尾矿坝体、排土场边坡地表形变的常态化监测工作。

Abstract: It is an important goal of national mine safety supervision to realize the identification and monitoring of major safety risks in key areas and key links of open-pit mines.Based on the actual needs of safety identification and monitoring of tailings dam and dump slope in open-pit mines,the Lanxian-Loufan iron mine area in Shanxi Province was taken as the re search area.A total of 92 small baseline interference pairs composed of 35 scenes of Sentinel-1A SAR data were used.Based on the DS-InSAR technology of distributed scatterers,the effectiveness and applicability of this technology applied to the monito ring of mountain surface deformation in regional open-pit mines were verified,and the surface deformation characteristics of tailings dam and dump slope in this area were analyzed and studied.The monitoring results show that the DS-InSAR technology can effectively identify the surface deformation of three tailings dams and three dump slopes in the study area.Considering that these tailings dams and dumps are in the operation stage,the surface deformation is mainly consolidation subsidence and self compacting deformation.Compared with SBAS-InSAR technology,the coherence of target points is significantly improved after phase optimization and reconstruction of DS-InSAR technology.The number of coherent points increases to 6.5 times,and the correlation coefficient of surface deformation is 0.81.It provides technical and data support for the identification of surface de formation hazards and stability evaluation of tailings dam and dump slope,as well as the study of surface deformation mecha nism.The research shows that Yuanjiacun Iron Mine and Jianshan Iron Mine urgently need to strengthen the normalized moni toring of surface deformation of tailings dam and dump slope.
