The Study of the Influence of System Development Parameters on the Intensity of Deposit Mining

The main goal of the study is to substantiate the influence of open-pit ore productivity and the parameters of the development system, which are interrelated, on the intensity of mining of the deposit. The study of the influence of the parameters of the development system and the open-pit productivity by ore on the intensity of deposit development must be carried out taking into account the relationship between the width of the working platform and the length of the mining front, ensuring the standard of reserves ready for extraction for the adopted open-pit productivity by ore. In this case, the relationship of the parameters of the development system is taken into account by means of graphical methods of mining and geometric analysis of the pit field. Changes in open-pit productivity by ore are possible due to changes in the parameters of the development system and lead to changes in the intensity of deposit development. At the same time, an increase in the slope angle of the working side of the open-pit due to a decrease in the width of the working platform leads to a decrease in open-pit productivity by ore, as well as the speed of horizontal advancement and the rate of deepening of the pit bottom. As a result of the studies, the relationship between open-pit productivity by ore, parameters of the development system, which are interrelated, based on the provision of reserves ready for extraction, and the intensity of deposit development was substantiated.
