RESULTS OF RESEARCH ON DETERMIN-ING THE DEPENDENCE BETWEEN DEFORMATION PARAMETERS BASED ON GEODESY AND RADONOMETRY DATA

Abstract

The article presents the results of analytical studies aimed at determining the empirical relationship between the deformation indicators of tension and compression based on radonometry data and the values of horizontal deformations based on geodetic monitoring data for the rock mass of the Severopeschanskaya mine site. The study used the results of radonometry and geodetic surveys conducted in 2023 to determine the possibility of using the ratio of the volume activity of radon-222 and thoron in the soil air to identify areas of tension and compression deformations within the Severopeschanskaya mine site. The results of geodetic monitoring over an eight-month observation period were used as parametric. The results of geodetic monitoring confirmed the reliability of identifying zones of decompaction and compression deformations in the rock mass using radonometry. As a result of the performed analytical studies, the dependencies between the values of deformations determined using geodesy and the deformation indicators determined using radonometry were established. The obtained dependencies allowed for the determination of quantitative values of horizontal deformations at radonometric measurement points. Using the approximation method, a map of the distribution of horizontal deformations within the industrial site was constructed. Although this method is less accurate than geodetic surveys, it provides a general picture of the distribution of deformations not only along the profile geodetic line but also across the area of the studied rock mass with minimal material costs.
