“…Underground mining-induced ground movement is considered responsible for disturbance of the natural ground surface, damage to man-made surface infrastructures, farmland and aquifers (Can et al, 2012). From the early stages of coal extraction, coal mining operators commonly start by extracting the most profitable coal seams, leaving the thinner, deeper, or less commercially viable coal seams unmined.…”

“…Protecting the surface, its natural, economic, and other values from the effects of mining is an important part of ecological endeavors [1,2]. In addition to general degradation, mining production is increasingly moving to urban areas, where much more important infrastructure is at risk [3,4]. The mining organization is therefore obliged to implement direct protective measures on the surface or underground infrastructure and water regime within the exploitation area [5].…”

Impacts of underground mining have been reduced by continuous environmental endeavors, scientific, and engineering research activities, whose main object is the behavior and control of the undermined rock mass and the subsequent surface subsidence. In the presented Velenje case of underground sublevel longwall mining where coal is being exploited both horizontal and vertical, backfilling processes and accompanying fracturing in the coal layer, and rock mass are causing uncontrolled subsidence of the surface above. 3D point clouds of the study were acquired in ten epochs and at excavation heights on the front were measured at the same epochs. By establishing a sectors layout in the observational area, smaller point clouds were obtained, to which planes were fitted and centroids of these planes then calculated. Centroid heights were analyzed with the FNSE model to estimate the time of consolidation and modified according to excavation parameters to determine total subsidence after a certain period. Proposed prognosis approaches for estimating consolidation of active subsidence and long term surface environmental protection measures have been proposed and presented. The C2C analysis of distances between acquired 3D point clouds was used for identification of surface subsidence, reclamation areas and sink holes, and for validation of feasibility and effectiveness of the proposed prognosis.

“…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.
