The purpose of the work is to calculate the stability degree of the ledge and the group of ledges in the quarry № 4 PJSC "TsGZK" over 30 meters and determine the size of the probable shift prism. Research method - analytical calculations to determine the stability coefficient of rock ledges over 30 meters by the method of algebraic addition forces along the curved shift surface. The conducted research and analytical calculations allowed to establish that the influence on the stability of ledges and groups of ledges of road embankment within the prism of probable of 0–4% is insignificant. The analysis of the initial surveying documentation, of September 19, 2019, in the quarry №4 of PJSC "TsGOK" allowed to identify 7 sections characterized by the embankment of roads within the prism of probable shift of rocky slopes over 30 meters. The influence of the load on the stability of the ledges and groups of ledges under consideration is insignificant. Product Description popup.authors Yechkalo Yuliia V Gerasymova Kateryna V.
