ON THE FEATURES OF CHANGES IN MINING AND GEOLOGICAL CONDITIONS IN CONNECTION WITH THE DEVELOPMENT OF THE YOSHLIK PORPHYRY COPPER DEPOSIT
Abstract
The article presents data on the possible deformation of rock masses in the Yoshlik deposit based on the results of studying the geological-tectonic structure of the deposit and the engineering-geological properties of the rocks, as well as based on the analysis of similar masses in the depleted Kyrgashinkan mine and in the Kalmakyr and Sary-Cheku deposits, where the extraction process is nearing completion. The possibility of occurrence of deformations of various nature and volume, as well as the development of other mining and geological processes and phenomena, due to the expansion of the quarry field, an increase in the depth of development, and the opening of waterlogged tectonic faults, leading to a decrease in the stability of the benches during the development of the deposit, has been substantiated.
