Definition of the ground surface deformations and constructions in the rock breakage zone

Abstract

The article discusses the issue of improving the efficiency of surveying and geodesic observations of deformations of areas worked up by underground mining. The authors made an analysis of the current state of the issue and based on this, it was proposed to use different approaches to solving the problem, taking into account the features of the observed object. The use of electronic tachometers for performing linear measurements using observation stations to study the processes of displacement of rocks and the earth's surface deserves attention. In this case, benchmarks can be determined from leveling. In studies of deformations in large areas of dumps or quarries, it is advisable to use the method of coordinate reference frames using GPS. The coordinates are calculated not only the magnitude of the deformation, but the direction of displacement. Modern digital methods allow you to explore inaccessible objects that are dangerous to perform work on them by traditional methods. The article provides an example of processing a digital survey made from an unmanned aerial vehicle. The possibility of using this method to monitor deformations has been proved, and to improve the accuracy of determining the values of deformations, it is advisable to improve the accuracy of image processing by including the use of additional characters in standard programs.
