In order to improve the accuracy of the prediction of ore flowability in the ore storage section of the ore pass based on numerical simulation and indoor similarity test, the parameters of the parallel bond model based on the slump and expansion test were introduced in the numerical simulation process. The numerical simulation results obtained by this method were highly consistent with the indoor similarity test. The results indicate a significant decline in ore flowability within the moisture content range of 0 to 9%. Particularly when the moisture content is 7%−9%, the ores are prone to blockages. Therefore, this specific moisture content range should be strictly avoided during actual ore drawing operations. When the moisture content is 3%−5%, the flowability of the ore is the best. It is suggested that the moisture content of the ore should be controlled in this range in the actual project. Furthermore, the study reveals that as the ore storage height increases from 20 m to 40 m, the flowability of the ore improves significantly, reaching a peak mass flow rate at 40 m. However, when the ore storage height is further increased to 60 m, the mass flow rate stabilizes and exhibits a slight decline.
