开采沉陷区地面设施的结构稳定性受到地表沉陷的威胁。明确和评估地面沉降的影响可以为建筑物、道路和桥梁等各种地面设施的建设和维护提供信息。利用小基线干涉合成孔径雷达（SBAS-InSAR）监测技术和地理信息系统（GIS）技术，对山西省阳泉市开采引起的地表沉陷及潜在危害区域进行了调查。具体来说，我们首先利用SBAS-InSAR监测，调查了2016年6月16日至2016年12月1日期间阳泉市的沉降面积和沉降率分布。然后，我们分类的地面设施，如建筑物，公路和铁路，并确定其分布使用空间分析，地理信息系统。最后，我们综合两种技术的结果，以评估各种地面设施的潜在损害引起的地面沉降。我们发现，总体而言，（1）阳泉煤矿地表沉陷严重，（2）部分沉陷区存在于高层建筑、公路、铁路等高水平限制设施中，可能造成潜在损害。本文的工作可供类似的工程应用参考。
Surface subsidence threatens the structural stability of ground facilities located in mining-induced subsidence areas. Clarifying and evaluating the influence of surface subsidence can inform the construction and maintenance of various ground facilities, such as buildings, roads, and bridges. In this paper, we investigated mining-induced surface subsidence and areas of potential damage in Yangquan City, Shanxi Province, by exploiting small-baseline set interferometric synthetic aperture radar (SBAS-InSAR) monitoring and geographic information system (GIS) techniques. More specifically, we first investigated the distributions of subsidence areas and subsidence rates in Yangquan City from June 16th, 2016, to December 1st, 2016, by exploiting SBAS-InSAR monitoring. We then classified ground facilities, such as buildings, highways and railways, and identified their distributions using spatial analysis using GIS. Finally, we integrated the results of the two techniques to evaluate the potential damages induced by surface subsidence for various ground facilities. We found that, overall, (1) surface subsidence has seriously developed in the Yangquan Mine and (2) some of the subsidence areas exist in facilities with high-level restrictions, such as high-rise buildings, highways, and railways, which may cause potential damage. Our work presented in this paper could be referred to and applied to other similar cases.
