Abstract: More than half of the explored reserves of valuable ores, precious metals and non-metallic raw materials are located in deposits of small and medium thickness [1]. Underground mining of such ore deposits is characterized by more frequent, in comparison with the mining of thick deposits, preparation of chambers for production excavation, a more complex system for delivering ore to places of loading into vehicles, and despite all the variety of technical and technological solutions, it still requires a significant amount of manual work labor. In this regard, research aimed at identifying and developing reserves for optimizing preparatory and auxiliary work during the development of small and medium-sized deposits is relevant. This article presents the results of a study of the influence of the quality of labor productivity planning in the treatment chambers of the Oktyabrsky underground mine on the dispersion of its shift productivity and the results of the processing plant. In particular, through time-lapse observations, it was revealed that the structure of work in the chambers differs significantly in the ratio of time spent on auxiliary work and main work, on the direct implementation of the technological process. This ratio changes up to 3 times. Three categories of complexity of treatment chambers are identified according to the criterion of the specific duration of auxiliary work. For each selected category of camera complexity, the consistently achieved average monthly productivity in them was determined. Based on an analysis of actual data on the work of Buribayevsky GOK JSC for 2023. It has been proven that planning shift productivity taking into account the criterion of specific duration of auxiliary work, reflecting the complexity of cleaning work in the chambers, can significantly increase the rhythm of the technological proces
