Scientific research discussed in the present article is focused on the determination of the vertical conveyance capacity in the process of mining minerals, while applying a mathematical calculation and verification of the calculation results by simulation. Input parameters for the capacity calculation include the transport cycle time. The article presents the results of measuring a transport cycle during the operation and a calculation of the transport cycle while using known formulas. On the basis of the observed findings, two methods of increasing the hoisting machine capacity were proposed. The first method is increasing the velocity from the original value of 6 m.s–1 to the velocity of 7 m.s–1. In this case, we achieved the daily capacity increase in 2-2.5%. The second method consisted in changing the hoisting machine acceleration and deceleration modes by which we achieved as much as 9% increase in the daily capacity. The article also describes a transport cycle simulation model, with its output being the number of work cycles parameter. The obtained parameter was used again in the capacity calculation. The simulation model was used in experiments for both, the current status as well as proposed solutions. The simulation model serves also for calculation verification.
