Purpose. In modern conditions, the problem of increasing the efficiency of the railway transport of industrial enterprises is very urgent, and, first of all, this applies to enterprises of the metallurgical and mining industry, which are the largest recipients and consignors of goods by the railways of Ukraine. In this regard, the purpose of the study is to develop measures to increase the throughput and carrying capacity of the railway infrastructure of a mining enterprise in the context of an increase in the transportation of raw materials. Methods. The analysis of the technical equipment and technology of the railway transport of a large mining and processing plant in Ukraine was carried out using the methods of graphical analytical modeling. Results. The track development of the mining and processing plant ensures the delivery of iron ore from the quarry to the crushing and processing plant. The plant is presented as a system for transporting raw materials from loading points to unloading points, in which the process of its consumption is uniform (unloading ore on the tracks of a crushing plant), and the process of its replenishment is uneven (loading ore at loading points). Smoothing the uneven supply of raw materials between the points of loading and unloading provides the track capacity of the station adjacent to the crushing plant. The carrying capacity of the existing railway infrastructure of the plant does not ensure the mastery of the estimated volumes of transportation of raw materials. Analysis of the results of graphical modeling of the mining and processing plant showed that the limiting elements are the processing capacity of the crushing plant and long distances between the loading points and the abutment station. Organizational and technical solutions are proposed to increase the throughput of the railway infrastructure of the mining and processing plant. Practical significance. The results obtained can be used in the implementation of recommendations aimed at increasing the efficiency of the functioning of the railway transport of the mining and processing plant in conditions of an increase in the volume of transportation of raw materials.
