Systematization of ore deposits is carried out according to geomechanical conditions on the basis of tectonic features. In total, more than 120 underground mines have been analyzed. Four models of the geo-environment are distinguished. They make it possible to differentially describe the nature of the change in the stress state with increasing depth. The efficiency and reliability of the use of typical geomechanical conditions of rock massifs for determining the field of application of geotechnologies is shown. Co...

The Makmal gold deposit is located in the Republic of Kyrgyzstan. As a result of mining operations, under the bottom of the quarry, an open worked out space was formed with access to the surface above each chamber and overhanging rock consoles. This mining situation at the field caused the danger of sudden collapses of rock consoles and the walls of the chambers of the separating pillar. In this article, in order to justify the method of filling the voids and choosing the technology for the extraction of the pilla...
