The problem of establishing the relationship between the working site width and the mining operations active front length in the open-pit, providing a normative ore reserve and its effect on ore output productivity is considered. It has been established that for a given ore output productivity, when determining the parameters of a mining development system, which satisfy standardized reserves, it is necessary to consider the size of the active area of the open-pit working zone, as well as the effect of the mining operations concentration on the cost price of the marketable mineral products. It is shown that in the process of determining the working site width at a given ore output productivity of the open-pit, only the length of the active front by ore and strip-mining at the time of assessment is considered. At the same time, the influence of a change in the working site width on it is not considered. On the example of a conventional openpit, the influence of the active area size of the open-pit working zone on the parameters of a mining development system that satisfy the normalized reserves for a given ore output productivity of the open-pit is shown. A method for determining the working site width and the mining operations active front length, which satisfy the requirements of the standardized reserves, for various options for the ore output productivity of the open-pit is described.
