Abstract

Based on the results of data processing of regular GPS surveying of point field stabilized in the selected location with an active underground mining of coal deposits, it is possible to monitor the development of creating of subsidence depression. One analysis to assist in better understanding of the ongoing processes is the spatial-temporal analysis of shifts of individual points, which serves as a basis for describing degree of influence of the monitored coalfaces on the progress of deformations of different parts of interest area.
