Abstract: A feature of the technology of the modern production process of a large quarry is the high duration of production cycles, sometimes decades. As a result, in order to maintain uniform production in the current period, stripping operations prepare for excavation a quantity of reserves that often multiply exceeds the production of the period, and writing off almost all of the current volumes of overburden and expenses of the period are being carried out only for current production. This leads to a significant distortion in the direction of increasing its cost, to reducing profits and income tax received by the state, to reducing owners' incomes and the market value of the assets of the enterprise.
With a long production cycle, the nature of the process of production, having a complex structure of elements in a wide intersectoral context, is described in detail in modern educational management literature [1]. However, in modern mining literature in the scientific community such generally accepted concepts of the structural components of the production process as the production cycle, work in progress, advancing overburden work (backlog) and other elements making up the process are practically absent in relation to the open pit mining method [2-4].
The backlog of work in progress is an essential and necessary element of the work of almost all enterprises. Backlogs in the open pit mines are formed from the volumes of the advanced stripping work in progress, stayed at various intermediate stages of the preparatory work production process.
Further development of modern mining production of competitive products requires in-depth studies of the real picture of the production process in quarries [5].
