In the mining industry, transporting rock overburden and ores from deep and medium-depth open pit horizons to the surface is a critical challenge. The most efficient solution is the use of cyclic flow technology (CFT) with steeply inclined conveyors (SIC). This paper justifies the application of a steeply inclined tubular conveyor at the Gleivatsky open pit of PJSC ‘Central Mining and Processing Plant’, Ukraine, detailing the design and calculation of key structural parameters across all conveyor sections. Key technical dependencies—such as belt speed, belt width, roller support pitch, and space filling—are related to mining and geological characteristics of the rock mass (including maximum piece size and strength) and conveying parameters (angle, height of ascent, and route length). The belt tension at critical points of the conveyor contour is calculated, along with drive and tensioning station parameters. For a specified conveyor route with defined lengths and inclined angles, a tubular conveyor design with a 3000tonnes/hour capacity is proposed. The conveyor’s total lifting height is 370meters. The drive system is a two-drum tandem with a belt girth angle of 430°, and power of 6300kW. The belt used is a 2200mm wide rubber rope conveyor belt. The conveyor bed section design includes 8 roller supports, each with 6 rollers; the section measures 12,000mm in length, 1300mm in width, and 2200mm in height. The practical significance lies in the validated application of steeply inclined tubular conveyors alongside quarry faces in cyclic-flow technology, enabling efficient transport between deep mining horizons and the surface.
