The mining science, unlike many other technical sciences, studies the processes that occur not in one place, but in moving faces. The primary task is to analyze the influence of the various factors defining the parameters of the quarry operational area and to define a possibility of mining operations’ concentrating on the individual sections of the quarry, taking into account their further development downdip and in-depth. The intensity of their movement depends on the surface and on the excavating equipment capacity. The development of open pit mining area in time and space is subject to certain rules. Thus, the initiating works providing the access to the deposit should be ahead of the work on the preparation of excavation blocks, and the latter coal extraction. The intensity of the implementation of this works is also associated with certain patterns of the quarry working area development. The article describes the calculation method for determining the cyclical size of the working area, as a function of some key points: the time of working area development; its speed vector; the direction of the depth of mining and the quarry field area.
