On control of stressed-deformed behaviour of rock mass at roadheading under rockburst hazardous conditions

By the 3D finite elements method the problem has been considered for the case of changing stressed-deformed behaviour of rock mass in the near-excavation zone with relief slots forming in the roof differentially remote from the face. The recommendations have been given for control over the rock mass stressed-deformed behaviour in the roof and face of the drift by making relief slots depending on the level of initial stress field in the intact massif.

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.
