· Can et al. used GPS data and levelling to determine surface displacements due to coal mining activities near the city of Kozlu in Turkey. Based on three measurement campaigns in a short interval of 15 months, they found horizontal displacements of up to 153 mm and subsidence of up to 97 mm. A thorough analysis of mining subsidence in the region of Karvina (Czech Republic) was carried .

· A static coal mine GPS observation network is first established and a leveling conjunction provides the normal height of the control points. An optimal model is selected to establish a regional quasigeoid by comparing different height anomaly fitting models. Based on established quasigeoid and collected leveling data, the height datum of monitoring coal mining subsidence can be built ...

· In this article, an appliion of the method to a coal mining area in China is presented. Support vector machine (SVM) model for GPS level conversion in the mining area is established, and a comparative analysis of SVM, BP neural network and polynomial established local quasigeoid in the mining area is conducted. Ground surface digital elevation model (DEM) of the mining .
· Methods of TLS for mining subsidence. Figure 1 is a schematic diagram of TLS used for monitoring subsidence in mining process. When coal seam is excavated toward position 1, observe the ground surface above the coal face using TLS, and then establish digital elevation model (DEM) in the mining subsidence area through scanning data (hereinafter referred to as DEM1).
· Surveying in the mining industry, both in openpit and underground mines, often goes hand in hand with terrestrial laser scanning (TLS), which is deployed to verify the spatial changes of mining works. Thanks to its high point density and high accuracy, TLS is a very suitable surveying technique for monitoring movements and deformations.
