“…To calculate the cost of ore mining, the actual costs of stripping operations for the equipment used were taken. exclude the development transport system (conveyor transport) on the upper bench [12][13][14][15]. Such dependencies show a strict correlation between the angle of repose of the blade and the re-excavation factor.…”

The current state of mining operations in the open pits of the Pokrovsky mining and processing enterprise has been analyzed, where the shortcomings of existing technological schemes have been identified. Technical and organizational criteria have been identified that must be met by technological schemes for overburden and mining operations for the open-pits of the Pokrovsky mining and processing enterprise, where conveyor transport is used. Five technological schemes have been proposed for the Pivnichnyi open-pit, which provide for the reallocation of the height of overburden benches and the movement of overburden only to internal dumps without the use of conveyors. The dependences of the height of the internal dump and its resulting angle of slope on the re-excavation factor for the proposed technological schemes were obtained. The indicators have been calculated at which the most operating efficiency of mining and transport equipment for the Pivnichnyi open-pit of the Pokrovsky mining and processing enterprise (MPE) will be achieved and complete extraction of overburden rocks with cross movement to the internal dump without the use of conveyor transport will be ensured, and the production capacity of the quarry is also given according to the demand for ore.

“…The criterion for assessing the effectiveness of the proposed mining system is the specific cost for strip-mining of 1 m 3 [19,20,21,22]. Therefore, we will calculate all cost items for this stripping site, and based on the obtained data, construct a histogram for calculating unit costs for mining the Zakhidnyi Quarry No.1 site (Fig.…”

The paper examines a complicated non-transport system for mining a gently sloping fireclay deposit using ESH-10/70 dragline excavators. The research purpose is to substantiate the technological scheme of stripping operations and determine their parameters to reduce the strip-mining costs. Theoretical research is performed using the following methods: methods of scientific analysis of theoretical research, as well as practices of project and production organizations; mining-geometric calculations; variant method for comparing and selecting a mining system. As a result, the dependence of the excavator block mining velocity on the entry way width has been determined, which makes it possible to study the relationship between mining and stripping equipment in time. The change in the re-excavation coefficient depending on the width of the dragline excavator entry way has been studied and its rational value has been determined. The practical value of the research results is in the substantiation of an effective system for mining a gently sloping fireclay deposit.
