“…They exhibit vertical and horizontal displacement components (Kratzsch, 1983). The horizontal displacements are centripetal for subsidence, and centrifugal for uplift (Müller and Preusse, 2018). Thus, the longitudinal direction, indicated by azimuth Λ, is oriented parallel to the isodeformation lines, and the transversal direction is downslope (centripetal) for subsidence, and centrifugal for uplift.…”

Deformation phenomena on Earth are inherently three dimensional. With InSAR, in many practical situations the maximum number of observations is two (ascending and descending), resulting in an infinite number of possible displacement estimates. Here we propose a practical solution to this underdeterminancy problem in the form of the strapdown approach. With the strapdown approach it is possible to obtain 3D-global/2D-local solutions, using minimal and largely undisputed contextual information. It is a generic method that defines a local reference system with transversal, longitudinal, and normal (TLN) axes, with displacement occurring in the transversal-normal plane only. Since the orientation of the local frame is based on the physics of the problem at hand, the strapdown approach gives physically more relevant estimates compared to conventional approaches. Moreover, with uncertainty in the orientation of the local frame and error propagation it is possible to assess the precision of the final estimates. Appropriate cartographic visualization using vector map with confidence ellipses enables an improved interpretation of the results.

“…Sroka and Preusse, working within the framework of a RAG-funded research project, developed a mathematical model whose formal mathematical structure is identical to the geometrically integral geodetic method of subsidence projection (Dudek et al 2020;Dudek and tajduś 2021;Müller and Preusse 2018). this method is based on the assumption that a rise in mine water levels leads to an increase in pore pressure in the rock zone that has been fractured by mining operations (Preusse and Sroka 2015;Sroka 2005;Sroka and Preusse 2009).…”

“…For example, the damage characteristics and the transmission mechanism of overlying rock strata were analyzed, and evaluated the forms of surface damage [29]. Denise Müller proposed that the differences in tilt subsidence or horizontal changes in length should be preferred to describe the relevance of mining damage on buildings [30]. Interferometric synthetic aperture radar (InSAR) time series analysis was applied to assess the amount of damage above coal mining areas, and a model of the relationship between the damage level to constructions and ground deformation due to mining damage was developed [31].…”

Mining-induced subsidence is critical for ecological environment reconstruction and damage prevention in coal mining areas. Understanding the characteristics of surface subsidence with multi-seam mining is the first step. Surface subsidence of different mining panel layout configurations was investigated by means of UDEC numerical simulation. Based on the simulation results, it was indicated that mining panel layout configuration had a significant impact on surface subsidence, including ground surface subsidence, horizontal displacement, crack propagation, and ground surface fissure development. The overlapped region of the upper panel and the lower panel is the key region, where existing bedding separations and strata cracks close and activate, the integrity and strength of the interburden layer are reduced, and the subsidence magnitude is enhanced. The subsidence profile of the overlapped region for the stacked configuration, external staggered, the edge of the lower panel internal staggered, two edges of the lower panel internal staggered are steeper and deeper, and the corresponding values of ground surface subsidence and horizontal displacement are greater than other regions. The ground surface fissures with the types of stepped, slided, and graben developed on the ground surface above the edge of the mining panel, and the development location is closely related to the strata movement edge. Because of the support activities of the reserved coal pillar, the ground subsidence of the external staggered (internal staggered) of the upper panel with the coal pillar is slight. The external staggered (internal staggered) and external staggered (internal staggered) of the upper panel with the coal pillar can be selected as the preferred layout configuration. The proposed description of surface subsidence of different mining panel layout configurations can be applied in subsidence prediction.
