Constant growth of the depth of mining and the intensification of mining pressure manifestations in the dynamic form,
result in the realization of special geomechanical investigations on the problem of protection from rock bumps. It is known,
that conditions and forms of rock destruction during underground mining are defined by a complex influence of three main
factors: total level of static and dynamic stresses within the elements of mining constructions, conditions and speed of
loading of the latter from the side of the loading system – rock massif. Rock bumps, as a rule, are timed to fleeting massif
movements of underworked massif rock. The analysis of rock-bump hazard conditions with the account of the regime of
loading reveals significant influence of the inequality in physical, especially strength properties of rock and ore building up
a massif, on the character of distribution of stresses and deformations within the loaded elements of mining constructions.
The results of the analysis are introduced of ore deposits development conditions and rock destruction forms during
underground mining in conditions of higher stress with the purpose of assessing their influence on the mechanism of rock
destruction in dynamic form.
Key words: rock pressure control; geomechanical conditions; rock-bump hazard; dynamic rock pressure manifestation;
static stress; dynamic stress.
