“…Radar interferometry technique provides a means to monitor earthquakes, volcanic movements, glacial movements and rebounds, landslides, surface deformations, etc. InSAR techniques have been used to determine manmade subsidences and surface swelling all over the worlds such as in Groninggen, Holland (Hanssen & Usai 1997); Pomona, California, USA (Ferretti et al 2000); Appin, Australia (Ge et al 2003); and Zonguldak, Turkey (Akcin et al 2010 Can et al (2011Can et al ( , 2012Can et al ( , 2013aCan et al ( , 2013b deal with the precise leveling and Global Positioning System (GPS) monitoring results for the basin to determine the mining-induced horizontal and vertical displacements and indicate the similar subsidence findings in the same study area. In Zonguldak-Kozlu Hard Coal Region, coal seams dip mostly at high angle, and their thicknesses are not uniform; therefore, mining subsidence problems are most likely to occur causing very serious problems with regard to urbanization.…”

Since Turkey is located on a region that is prone to the risks of natural disasters like earthquake, flooding, and avalanche; a majority of the residential areas are facing these risks at various levels. Before determination of these risks, taking action in order to decrease the vulnerability levels of the residential areas will help keep the damage at the minimum level in case of a disaster. Urban planning decisions which are made in accordance with vulnerability studies aiming to determine natural disaster risks will not only help prevent loss of life but also help decrease negative social and economic effects of disasters. The Zonguldak city has been chosen as a case study area since Zonguldak metropolitan area has endured almost all kinds of threats that a city can face. In this study disaster-producing factors in the area are primarily considered which can be named as topography, destruction of forest lands, geological and karstic structure, mining activities, and misuse of the land, and later risk assessment is conducted with geographic information system (GIS). It has been assessed that more than half of the buildings within the study area were constructed in areas not suitable for housing. It is concluded that there is a need for urgent urban development plan for the city.

“…In order to protect the lives of people and their property, as well as the complex environment, it is essential to constantly investigate any movements in the subsidence on the earth surface even after mining has ended [2,13,14]. The most investigated movements in the subsidence with their prediction based on threedimensional (3D) modeling are on coal fields [3,5,11,12,[14][15][16][17].…”

“…), which are used extensively up to now or are currently increasingly using advanced methods of the satellite technologies within the Global Navigation Satellite Systems (GNSS) based on the US Global Positioning System (GPS), Russian Global Navigation Sputnik System (GLONAS), European Galileo, and Chinese Compass (BeiDou II). At present, very specific measurement technologies such as Interferometric Synthetic Aperture Radar (InSAR), i.e., the radar surveying technology, and Light Detection and Ranging (LiDAR), i.e., the laser surveying technology, are increasingly being applied to deformation measurements [14,15,[18][19][20][21][22][23][24][25][26]. The deformation vectors are the outputs of 3D data processing from the abovementioned geodetic measurements of deformations (deformation measurements) of the earth surface or building structure objects, but several geodetic measurements are combined and thus confirmed by some physical measurements based on the measurement of stress and strain states.…”

“…Most of the monitoring stations consist of a network of firmly stabilized points (geodetic network) on the surveyed earth surface or on surveyed buildings and other engineering structures. By various geodetic methods, measurements are made on these points of the geodetic network to determine their 3D positions (i.e., coordinates X, Y, and Z) in the given Cartesian coordinate system [5,14]. During the realization of long-term (multiyear or even several decades) geodetic measurements, undesirable and unpredictable obstructions and interventions into the monitoring station and so into the geometric structure of the geodetic network may also occur.…”

Mining activity influences on the environment belong to the most negative industrial influences. Mining subsidence on the earth surface is a result of underground mining. The present study deals with the theory of specific procedures for solving the deformation vector in the case of an objective disturbance of data homogeneity in the geodetic network structure of the monitoring station in monitoring mining subsidence. The theory was developed for the mining subsidence created on the earth surface of the mining landscape, where the abandoned magnesite mine Košice-Bankov in the East of Slovakia was operated for many decades in the twentieth century. The achieved results and outputs were implemented into the GIS tools for the plan of the process of gradual reclaiming the entire mining landscape of Košice-Bankov. The aim of the deformation measurements was to determine the exact boundaries of the subsidence edges with the residual movement zones for the purpose of comprehensive reclaiming the devastated mining landscape. Some numerical and graphical results from the deformation vectors survey in the abandoned magnesite mine Košice-Bankov are presented. The obtained results in GIS were supplied for the needs of the Municipality of the city of Košice to the realization of the reclaiming work.

“…They have shown that the geometry of the subsidence bowl is different and larger than the one assumed from groundbased geodetic measurements. Can et al (2013) have investigated surface, mining related, deformations on engineering structures in a coal basin in Turkey with precise levelling and static GPS observations in a monitoring network. They have identified active and residual subsidence effects on selected engineering structures.…”

Land subsidence in the area of the city of Walbrzych (SW Poland) has been a consequence of underground mining of hard coal. Exploitation of multiseam deposit took place for several 100 years and ended in the late 90'ties of the twentieth century. During this time, many buildings and constructions were affected by subsidence-related damages and new landforms including mining waste dumps have developed on the surface in a consequence of underground extraction of coal. Previous studies indicated that cumulative subsidence calculated with the empirical Knothe theory reached -22 m, whereas calculations based on results of cartographic data processing showed more than -30 m (± 3 m) pointing to insufficient reliability of traditional methods when applied in complex and complicated conditions (multiseam and steeply inclined deposits). Present-day height of manmade landforms in areas affected by subsidence reaches 63 m (± 3 m). Therefore, in the presented research, a weighted spatial regression method has been proposed for analysis and modelling of mining induced land subsidence. The study concerned the former Walbrzych coal mine area and the 1886-2009 period. The subsidence modelling has been done in geographic information systems with geographically weighted regression (GWR) method that allows for spatial variability of subsidence factors. Four, out of the analysed seven, subsidence factors were identified as significant (thickness, inclination and depth of coal levels and surface slope) and used as independent (explanatory) variables in construction of the subsidence model with the GWR method. The validated model was used to estimate subsidence in up to now unmapped areas transformed by manmade landforms. The maximum predicted subsidence in these parts for the 1886-2009 period reaches -10.5 m. In the result, a spatial representation (hybrid map) of subsidence for the entire Walbrzych coal mine has been produced.
