The study of the collapse zone by remotemethods

Abstract

The aim of the research is to choose an effective remote method for surveying the area located above the space mined by underground mining. Often in separate sections of these territories funnels and dips are formed that do not allow the use of methods with finding the performer directly at thesepotentially dangerous sites.The research methodology is based on the implementation of survey work in the territory of the Ordzhonikidze mine, where undergroundmining is influencing the state of the groundsurface and buildings.In this case, various remotesurveymethods were used. An analysis of the results of the survey work made it possible to determine the most effective method for studying dangerousareas in which horizontal and vertical deformations are observed.As a result of research, special attention was paid to the use of modern remote sensing methods for the territory of the mine. As a result of the analysis of the survey using remote methods,the expediency of applying the method of terrestrial stereo surveyis determined, which has the necessary accuracy, and at the same time it is quite operational.The scientific novelty of the obtained results lies in the fact that the effectiveness of the use of ground-based digital stereo surveyfor studying the deformations of the groundsurface and objects located in the mine and adjacent areas that are undermined by underground mining has been proved.The optimal conditions for performing stereo surveyof the groundsurface and objects of these territories are determined, and a scheme for performing the binding ofsurvey stations is selected.The practical significance of the research is to study the deformations of the groundsurface and buildings on the mine territory and adjacent areas, terrestrial digital stereo surveywas used, which made it possibleto quickly determine horizontal and vertical deformations for a large number of points with the necessary accuracy.
