چکیده
|
The article is devoted to the analysis of approaches to modeling the stress-strain state of a block rock mass in the vicinity of a single mine workings and in the area of rock cantilever influence during the development of the khibiny apatite-nepheline deposits. the analysis of the existing in international engineering practice ideas about tectonic disturbances as a geomechanical element and the experience of predicting the stress-strain state of a block rock mass was carried out. on the basis of the analysis, the formulation of the basic modeling tasks is carried out and its main results are presented. methodological recommendations for solving similar problems were developed.
