This paper presents an analysis of observations of the displacement of the rock mass at the site of the underground machine hall of the Rogun hydropower plant during its completion. The main features of the displacement of the rock mass are considered and the advantages of using multipoint extensometers to observe the state of the rock mass are noted.
