On distribution of tectonic stresses in the Lovozerskaya blocked intrusion

Regularities of horizontal tectonic stresses' distribution in the Lovozersky rock massif have been researched by the boundary elements method. Variations of influence of geological structure and deep blocks which separate the rock massif by radial fault zones have been considered. Stresses distribution has been shown on the plan in accordance with the data on geological and blocked structure. Possibilities of rock massif destruction in the vicinity of excavations at the Umbozero and Karnasurt deposits have been studied.
