Abstract

Underground hard coal mining causes surface deformations. When the mining operations are conducted beneath linear objects, such as motorways, there is a risk of deformations of the axis of the road and its horizontal and vertical alignment (additional bends and vertical curvatures, longitudinal inclinations, deformations of cross-sections). In the areas subjected to mining operations, mining plants conduct geodetic monitoring. Due to their labour intensity and costs, geodetic measurements are usually made only a few times a year. The article discusses the possibility of applying Interferometric Synthetic Aperture Radar (InSAR) to monitor the subsidence of the vertical alignment of motorways caused by mining operations and its advantages and disadvantages compared to the currently used methods of geodetic measurements. The tests were conducted in two sections of motorways within the Upper Silesian Coal Basin (Poland) in the areas of intensive hard coal mining operations. Radar imaging of the surface made by the European Space Agency's (ESA) satellite Sentinel-1 equipped with the Synthetic Aperture Radar (SAR) was used.

应用合成孔径雷达干涉测量法监测跨欧洲交通网(TEN-T)的地表变形——以波兰上西里西亚煤盆地采矿作业地区的高速公路为例
地下硬煤开采引起地表变形。当采矿作业在直线物体(例如高速公路)下面进行时,道路的轴线及其水平和垂直方向有变形的危险(额外的弯曲和垂直弯曲、纵向倾斜、横截面变形)。在进行采矿作业的地区,采矿厂进行大地测量监测。由于他们的劳动强度和成本,大地测量通常一年只进行几次。本文讨论了应用干涉合成孔径雷达(InSAR)监测采矿作业引起的高速公路垂直走向沉降的可能性,以及与目前使用的大地测量方法相比的优缺点。试验是在上西里西亚煤炭盆地(波兰)密集开采硬煤地区的两段高速公路上进行的。使用的是欧洲航天局(ESA)的哨兵1号卫星(Sentinel-1)搭载合成孔径雷达(SAR)拍摄的火星表面雷达图像。
