Paper demonstrates the importance of substantiating the reserves volumes ready for mining in extraction units, in accordance with the mine output capacity, averaging mode and reducing the variation in the mined product quality. Rational methods of planning mining operations based on innovative technological solutions to achieve high-quality ore mass uniformity in terms of mineralogical composition are presented. Optimization of mineral extraction scheduling is possible with a comprehensive analysis of the existing situation and determining a well-founded method for mining operations. Averaging the mined ores content by two components requires a change in their volume planned for separate panels. Based on critical analysis and personal analytical research, a new method has been developed for averaging the mineral raw materials content. The method of ore content bottom-hole averaging in underground mining is substantiated, taking into account the output distribution over extraction units and obtaining a uniform quality of the extracted raw materials. The proposed method of averaging the minerals quality differs from the existing ones by the optimal ore volumes distribution in accordance with their content directly in the mined-out faces of the panels during the period of the field exploitation by underground method.
