This article discusses the expansion of the existing tailings facilities No. 1 and No. 2 of the Bozymchak concentrator to change the method of transportation and storage of 16.7 million m3 of enrichment tailings over the life of the facility. The tailings storage facility will receive semi-dry tailings containing flotation beneficiation products from the Bozymchak copper-gold bearing ores. Based on the results of detailed seismotectonic and geophysical surveys conducted at the base of the Bozymchak waste dump, it has been established that the calculated peak ground accelerations in this area can reach 0.3-0.35g. This corresponds to 8 points on the MSK-64 intensity scale. Considering the special requirements for ensuring stability of the tailings dump, an alternative method of calculating the stability of the slope parameters was additionally adopted, using the analytical method of Professor G.M. Shakhunyants.
