Оптимізація автомобільного транспорту та навантажувального обладнання на кар’єрах з видобування щебеню

The article examines the problem of improving productivity at crushed stone quarries through optimization of motor transport and loading equipment. The limitations of the existing fleet of dump trucks and loading machines, as well as the geometric parameters of transport trenches that prevent the use of traditional heavy-duty two-axle dump trucks, are analyzed. The feasibility of using modern three-axle dump trucks with optimized overall dimensions in combination with appropriate loading equipment is substantiated, which ensures an increase in body volume with a smaller vehicle width and a rational ratio of excavator and dump truck parameters. It is proven that the implementation of a coordinated transport-loading complex allows for organizing efficient two-way traffic in trenches of limited width and increases the overall productivity of mining operations by 25–30 %. The research results can be used in modernizing transport systems of existing quarries and designing new mining enterprises.
