The parameters of underopencast rock mass stress-strain condition for Koashva deposit are defined. The estimation of influence of surface development with opencast on the stress-strain distribution in the mass is revealed. Research is revealed with appliance of finite-elements method.
The parameters of the stress state of nearbord massif of deep open pit on the example of the field development of the V.Grib. This research was done by numerical simulation using finite elements method.
The analysis of soils stress-strain condition for different lining including in work period retards from tunnel’s face with applying of finite-elements method is adduced. The graphical relations of stresses, displacements, soils inelastic area configuration were obtained. According to these relations final graphical relation of temporary grouting influence for permanent lining stress-strain condition was developed.
In this learned article the analysis of the volume stress-strain condition of the soils in the tunnel’s face in the cases of different repulses of support lining with applying of a finite-elements method is adduced. The graphic relations of stresses and displacements of the soils is developed and with respect to these relations the influence of the magnitude of repulse of support lining at the volume stress-strain condition of the soil massif is defined.
