Abstract: The increase in the extraction of coal by the open method leads to an increase in the negative impact on the environment and the social situation in the region, so an urgent task is to use the underground mining method in the operating sections. The transition from open to underground, in the conditions of a single deposit, is usually called a combined development method. Definitions of the open-underground (combined) method of development and its classification for coal deposits, yet. The analysis of the open-underground (combined) method for the development of ore deposits, open-underground coal deposit research with examples at operating enterprises was carried out. As a result of the study of the issue, the notion and variant of classifica-tion with the features of the conditions of application of open-underground (combined) development for coal deposits are formulated. The use of an open-underground method for the development of coal deposits will increase the life of the field by completing the extraction of reserves, use a single infrastructure of the enterprise, reduce the cost of building mines, reduce the number of sections, in favor of the underground method, since most of them are located near settlements. The ecological situation in the region requires further study of the open-underground (combined) method of development of coal deposits.
