Abstract
The authors present the formulation and solution of a problem on the efficient engineering data of multi-drive high-duty belts for bulk coal. The theoretical framework for calculating the belt thrust includes the main equation of the belt conveyor dynamics, and features of calculations in stationary mode and in starting conditions with the regard to horizontal and vertical curvature of the belt route. The rational width and production capacity of a belt conveyor are substantiated. The hauling power and capacity of drives of a multi-drive belt are calculated. The strength test of a selected belt is performed. The calculation using the developed program LENTA 1.0 is presented as a case-study of a multi-drive belt conveyor in Inaglinskaya Mine in the South Yakutia coal field.
