Abstract: The article considers the most common technologies for the development of flooded sand and gravel deposits, and proposes a method for selecting mining equipment depending on the content of the gravel component in the useful stratum. The relevance of the work is determined by the need to optimize technological processes in the quarries of building mineral raw materials in the face of rising prices for technological equipment, energy resources, as well as rental rates. Research methods consist in a systematic analysis of the state of the construction industry in the field of mining of non-metallic minerals in the Moscow region, an assessment of the fleet of modern mining equipment, and technical and economic calculations of the effectiveness of the proposed solutions. The effective application zones for different types of mining equipment were established, the calculation of technical and economic indicators of development on the example of a sand and gravel deposit was made. The results of the above research can be useful to designers and subsoil users in the field of development of common minerals. The area of effective application of the considered technology is partially flooded deposits, represented by sand and gravel material, with relatively stable structure and thickness of the useful thickness, classified according to the complexity of the geological structure to the 1st and 2nd groups according to the "Classification of reserves and forecast resources of solid minerals" (order of the MPR of the Russian Federation dated 11.12.2006 No. 278).
