Abstract: The urgency of the discussed issue. Geochemical studies of coal seams of many deposits indicate that some seams containing valuable chemical elements in industrial concentrations for extraction can be considered as ore-bearing and should be developed using selective mining technologies. The main aim of the study. Generalization of the accumulated experience of underground selective mining of minerals through systematization of technological schemes by distinctive features. Choosing possible options for organizing selective coal mining in specific mining and geological conditions. The methods used in the study. To systematize technological schemes of underground selective mining, the method of facet classification is used, in which many variants of technological schemes are characterized by a set of characteristics on the basis of which it is repeatedly and independently divided into cells containing certain values of technology features. The results. Systematization of technological schemes for underground selective mining of coal seams al-lows grouping technologies according to certain criteria (goal, division into layers, cutting of enclosing rocks, the way of rocks delineation during their cutting, etc.) and, depending on mining and geological and mining conditions, by the analogy method choose the most rational variant.

Key words: coal deposit technological scheme selective mining separation of flows valuable chemical elements systematization
