ABSTRACT
Solving the problems of geo-mechanics that contribute to achieving the stability - reliability of mine workings involves the knowledge of the rheological behavior of rocks. We emphasize some of these issues, namely: clearing up the natural stress state; characterizing the deformation behavior of the rock massif; the secondary stress - strain of rocks around the main horizontal mine workings; characterization of geo-mining stability conditions where the galleries will be executed; studying the manifestation manner of the pressure and its calculation in the context of rock massif - support system – time mechanism of interaction; rheological characterization of the consolidated rocks, etc. This paper presents the manner of approaching the rock – support interaction problem for the sedimentary rocks from the Jiu Valley taking into account their rheological classification. Knowing the rheological behavior has implications in solving the problem referring to the mining pressure and its calculation in the context of rock massif – support system – time mechanism of interaction.
