Приликом израде подземних просторија у стјенској маси долази до нарушавања природне равнотеже напонских стања стијенског масива који су владали прије израде тих просторија, при чему долази до појаве прертасподјеле напона и његове концентрације у појединим правцима и тачкама, односно долази до појаве пластичних деформација које су праћене ломљењем стијенске масе и кретањима материјала према откопаном простору...
During the construction of the underground stopes in the rock mass, comes to
disrupting the natural balance of rock mass stress states that existed prior these facilities
in and leads to the redistribution of stress and its concentration in certain directions and
points, and comes to the appearance of plastic deformation, that are monitoring
hydraulic fracturing rock mass and movements of materials to the excavated area. The
main task of this thesis is to develop a model of rock massif around opening. The
applicability of the model will be displayed for the model constuction of the opening for
bauxite ore deposit "Podbracan" Milici, in order to estimate stress and deformation of
the rock mass around the openings. According to the basis of rock mass behavior
around the stope it is necessary to ensure the selection of adequate support of openings
for short periods and ensuring that openings for a longer period in order to prevent their
caving. The model will be presented in this thesis g...reatly helps to the decision on the
basis of the defined criteria and interpretation of stress conditions, for support elements
for underground openings in an unstable work environment and thus provide capital for
the period rooms of the mine life of the mine . In order to select the optimal premises
opening for a given work environment and the choice of supporting construction in
order to improve the safety of underground stopes and facilities and people, the problem
is solved through the explanations of all parameters which have influence, the specific
methodologies for the calculation and interpretation of data applied model. The results
will serve as a basis for the formulation of mathematical algorithms depending on the
certain parameters and comparative analysis of the impact of stress conditions for a
concrete underground opening in the ore deposit "Podbracan", Republic of Srpska.
