A method for determining the parameters of sound design elements of systems development of ore deposits in relation to a whole different purpose. Showing examples of methods for the conditions of ore deposit Yuzhnoe, Elkon uranium district.
The three dimensional stress distribution in tunnel set with allowance for relative influence and building sequence is investigated. To complete the task the finite elements analysis was used. The values of stress concentration factor and conformities of stress distribution in the «lining – mass» system are estimated. The relative influence of each tunnel in tunnel set with allowance for building sequence is identified.
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 parameters of the stress state of nearboard massif of deep ore pitas an example the development of apatite-nepheline Koashvinskoe deposis. This research was performed by numerical simulation using finite elements method.
Finite element analysis of soil – pile interaction for two different design schemes is done. 3d analysis and stage construction is considered. As the results of FEA modeling vertical displacement of soil and subsidence trough for different stage of construction are drawn and analyzed.
The main features of the entries supports in theinfluence zone of open pit and second working are established. Research was carried out using a numerical modelling by finiteelements method.
Result of research is definition the zone of influence of sewage treatment works and their character for developing nearbord stocks Koashva opencast. The analysis of changes in the stress-strain state of massif around development workings in stages mining substages depending on their position relative to cleaning area. The research was carried out using a numerical modelling using the finite elements method.
