Abstract

Pipeline hydraulic transportation is widely used in underground and open-pit mines, coal preparation plants and external plant utilities to move various rocks. Mixing with water, coal and rocks due to different granulometric and petrographic parameters turn into different types of hydraulic mixtures and are characterized by certain movement patterns inside the pipeline. One of the types of hydraulic mixtures is the tailings of copper ore mining plants. This paper presents the results of research on the particle size distribution and hydraulic dimensions of these hydraulic mixtures, as well as a formula for calculating the particle drag coefficient calculated for the studied hydraulic mixtures.
