Estimation of Mining-Induced Horizontal Strain Tensor of Land Surface Applying InSAR

نویسندگان

چکیده

Horizontal strains related to mining-induced subsidence may endanger infrastructure and surface users’ safety. While directional horizontal should be well determined, appropriate solutions for a complete assessment of the terrain deformation field are still required. As result, presented study examined new method calculating strain tensor based on decomposition satellite radar interferometry (InSAR) observations into vertical azimuth look direction (ALD) displacements. Based geometric integral model, we tested our experimental data before applying it an underground copper ore mine in Poland. In case study, displacement was determined using Multi-Temporal InSAR Sentinel-1 data. The model relative error did not exceed 0.02 at ? = ±0.003. For land up ?167 mm ALD displacements ranging from ?110 +62 obtained, whereas extreme values ranged ?0.52 mm/m +0.36 ±0.050 mm/m. Our results demonstrate high accuracy determining tensor. approach can broaden environmental impact worldwide.

Optimizing land leveling by applying warped surface

In this paper we develop a new approach for land leveling in order to improve the topology of a large area for irrigation or civil projects. The objective in proposed model is to minimize the total volume of cutting so that technical requirements of land leveling such as suitable slope and standard ratio of cutting to filling and maximum penstock point’s height are considered. We develop a warp...

Estimation of Alpine Permafrost Surface Deformation Using InSAR Data

The detection of active rock glacier and the quantification of the observed surface movement as well as its temporal change using the D-InSAR method are presented. An average deformation rate of -7.7 mm/35 days in the radar lineof-sight, in the summer of 1992, was estimated. Whereas, the corresponding geodetic measurement, vertical component of 3D flow velocity, was about –8.0 mm/35 days. Addit...
