STUDY OF STRESS-STRAIN STATE OF ROCKS
Keywords:
stress-strain state of rocks; rock burst hazard; slot unloading method; geodynamic and tectonic conditions; Kochbulak and Kyzyl-Alma deposits.Abstract
The article discusses the issue of studying the stress-strain state of rocks in the
ore deposits of Uzbekistan. A complex of studies of the stress-strain state of rocks was carried out.
Features of geodynamics, tectonics and field development conditions are taken into account in the
work to determine the critical depth of occurrence of rock impacts, as well as to obtain the most
complete picture of the stress-strain state of the studied deposits. The proposed method of
assessing the impact hazard of deposits is the most relevant for this period, due to the deepening
of mining operations to a critical level and the manifestation of rock pressure in a dynamic form
at these depths. The article also provides specific results of the critical depths of occurrence of
mountain impacts for various lithological strata in relation to the conditions of the Kochbulak and
Kyzyl-Alma fields.
