The article describes the principles of the calendar planning in the present-day geological-and-mining systems of the open-pit and underground mining. At present, a set of tasks was outlined being solved with using these systems at ore mining plants and design companies. A common approach to data preparation for the calculation of a calendar plan in the open pit and underground mining is described, including the determination of geological, technological and economical parameters to obtain the co-variant results of calculations. The advantages of introduction of geological-and-mining systems into the field of designing work are shown.
