Abstract: The coal mining industry is currently in need of increased competitiveness in the domestic market. The authors propose a comprehensive approach to improving the efficiency of production of high-quality thermal coal, which is one of the promising types of fuel due to its high quality characteristics. The article describes the technology for obtaining graded coal in the bottomhole conditions of a cut and delivering the resulting energy product in specialized containers to the consumer, which allows maintaining stable qualitative and quantitative indicators of the product at all stages of the production and logistics process. The technical feasibility of placing a processing unit in the form of a mobile crushing and screening plant in the working space of the face is substantiated, transport and technological schemes for placing equipment in different types of entrances are given, for each of which the placement conditions are calculated. A description of a specialized vehicle based on a dump truck, converted with a platform with specialized containers installed on it, is presented. A method for determining the overall dimensions of the platform is given, taking into account its layout by specialized containers of different sizes. An assessment of the economic efficiency of the proposed technology has been made, the rationale for which is based on a comparison of the cost of obtaining and delivering sized coal using traditional and proposed technology.
