Essay

In the thesis, model rheological phenomena in underground workings was proposed and investigated based on numerical modeling and results of field measurements, it was called " heaving rock ground". This phenomenon is typical for workings, that underlay at sufficiently large depths. In the thesis dependence was result, that allows to calculate the critical occurrence depth. Hypothesis of bifurcation energy state of rock mass around the workings located in elastic-plastic state was basad of idea. Parameters were worked out on the numerical finite-element model, at which there is a transition model from one state to another, with lower levels of potential energy. Field research were performed under conditions PSP "Shakhta Dobropil's'ka" VAT "DTEK - Dobropillyavuhillya". Comparison obtained data with the results of numerical modeling allowed to assert that proposed model of heaving rock ground is adequate and allows substantiated to approach to calculating the load on the bolting and choice its structural elements. Proposed option of combined frame- anchor bolting was accepted by mine to implementation. The expected economic effect from the proposal will be 785 hrn./m.
