Abstract: The critical condition of the complex of sloping separation (CSS) including concentrating installation, a crusher, the bunker and three galleries is considered. By results of engineering-geological researches and geophysical surveys it is established that formation of zones of the weakened basis soils owing to a landslide of the bulk massif is the main reason for dangerous deformations of the bases of designs. For justification of parameters of injection strengthening of soils the complex model operation including the forecast of deforma-tions of designs at the natural and strengthened bases, the analysis of an intense strained state of soils on the most dangerous site is carried out. Effectiveness of the accepted scheme of injection strengthening for elimina-tion of the critical condition of an object is confirmed. At the same time, the considerable calculated horizontal deformations of the base of one of support of KNS gallery for which prevention it is recommended to provide a padding number of injection wells with a depth below razuplotneniye border are established.
