. Significant share of the costs for deep quarries is the cost of rock mass reloading from the “assembly transport” to the main transport make up a considerable proportion in open pit development costs. Portable handling systems with bunkers are used, the parameters of which are determined by several methods. Methodology. In this work, when determining the capacity of the bunker, two approaches have been considered: deterministic – transport systems operate at nominal conditions; probabilistic – transport systems operate with their inherent unevenness. The methodology adopted is based on the geometry of the bunker in the configuration of the “inverted obelisk”, as the most productive system. Formulas to calculate the technological and geometric capacity of the bunker have been proposed. The proposed method parameters design takes into account assembly (automobile) transport arrival rate, which is described by the Poisson distribution and railway transport arrival rate described by the distribution of Erlang. Several numerical examples reveal practical application for bunker parameters determination. 112 "Izvestiya vysshikh uchebnykh zavedenii. Gornyi zhurnal". No. 4. 2020 ISSN 0536-1028 Results. The significance of the required additional bunker volumes has been justified in order to make up for cyclic transport vehicles irregular operation within combined transport complexes.
