Abstract. Ore output is one of the main parameters of the open pit, which defines economic figures of any mineral opencast mining. The objective of the study is to improve methods for determining open-pit productivity with taking into account the required reserve volume available for extraction. The method for determining open-pit productivity has the following idea in its basis: mine productivity is to be determined basing not only on maximum intensity of mining operations (maximally possible arrangement of mining excavators), but also with taking into account interaction of width of operational area and length of active stripping front, which ensure a required volume of reserves available fo area width impacting on stripping zone length and volumes available for extraction. The results of completed studies may be used by design organizations and mining enterprises for evaluating any mine productivity.

Keywords: width of operational area, length of active stripping front, open-pit productivity, reserves available for extraction.
