Abstract

Summary

The report is devoted to the study of rock masses deformation problem in the salt mining areas. The results of geodetic and geophysical researches, carried out in 2017–2018 on the Khotin field area of the Kalush salt mine, are presented in the paper. Geodetic surveys were performed on five profile lines using the method of high-precision geodetic leveling. Geophysical electrical explorations have been conducted by two methods – TDEM sounding (time-domain electromagnetic sounding) and by the natural electrical field method. The obtained results made it possible to estimate the rock masses state, to determine the inter-chamber pillars deformation degree of the Khotin mine field. The mathematical modelling of the stress state was carried out taking into account the presence of a specific object of high risk – the gas pipeline, which resulted in predictive models of the earth’s surface subsidence in the studied territory.
