SSESSMENT OF THE STABILITY OF THE ISHTAMBERDY TAILINGS DAM STRUCTURE
Keywords:
hydraulic structures, tail farms, factor of safety, strength storage, semi-dry tailings depositsAbstract
This article discusses three ways of stacking the flotation enrichment tailing material of the Ishtamberdy field’s coaxial factory, in connection with the change of gold extraction technology and introduction of the «Carbon in pulp» method into the process of tailing processing or «coal in pulp». This would also entail a change in the capacity of the tailing basin from bulk storage to dry storage. The stability factor calculated for each individual calculation, taking into account all the links and interactions, is the main indicator for choosing one of the tailings management techniques and therefore for assessing the stability of the tailing management facility design rather than for individual sites. The two-dimensional stability analysis of the slopes was carried out in accordance with the SRM extreme balance method using the MIDAS GTS NX software under static and pseudo-static (seismic load) conditions.
