Relevance. Reducing the cost of mining and transporting rock in quarries is one of the main factors affecting the cost of finished products. Today, belt conveyors are the most cost-effective means of transporting rock worldwide. Therefore, their use provides significant economic advantages-specifically, a 30–40% reduction in transportation costs. Despite these undeniable advantages, conveyor systems face a critical issue that significantly reduces their overall efficiency. Objective. Determination of the stress-strain state of conveyor belts during interaction of rocks by mathematical modeling. Methods. The research is based on modern computing tools – Ansys Workbench, MathCAD, and Maple – which enable the creation of 3D models, numerical calculations, and regression relationships. Single-and two-factor models were constructed to evaluate the stress-strain state under various operating conditions and identify optimal operating parameters. The stress-strain state of the conveyor belt occurs under the influence of powerful impact loads when rock falls from the transfer hopper. These dynamic forces cause localized damage, transverse cracks, and punctures, leading to premature and frequent belt ruptures. Therefore, the development of scientifically based approaches to optimizing the operating parameters of transfer units is needed. The results was established that optimizing the geometric parameters of a conveyor transport transfer point (a 5.4-meter-high belt conveyor hopper) can ensure minimal loads during contact between the rock mass and the conveyor belt for this design. The stress state of the conveyor belt was determined depending on the belt speed and the transfer point hopper height using single-and two-factor regression models.
