Geo-Ecological Consequences of the Closure of Coal Mines of Donbas (Based on Radio-Location Satellite Surveying Materials)

Abstract

The article considers the intensity of the subsidence process of the given surface of the territory of the Central coal-mining district of Donbas from 2015 to 2021, according to radar data from the Sentinel-1 satellite. There are 26 mines on this territory, most liquidated by completely uncontrolled flooding of mining operations without further control of the hydrodynamic regime. This study aims to determine the dangerous zones formed due to soil subsidence to rank the territory, particularly minefields, according to the degree of degradation processes (on the example of the Main Anticline of Donbas). The satellite-based radar differential Interferometry (DInSAR) methodology based on the SNAP program was used to construct a map of the Earth's surface vertical movements. The obtained results show that on a regional scale within the region from the northwest to the southeast, there is an increase in the amplitude of the vertical movements of the daytime surface, which coincides with the direction of the rise in the intensity of neotectonic movements of the entire territory of Donbas. It was established that the part of the works is divided into two regions according to the characteristics of the manifestation of local upward movements: northwestern and southeastern, which are clearly distinguished by the morphology of their constituent structures of the field of the local component of the vertical movements of the Earth's crust.
