Abstract: The objective of this work is to establish the patterns of temperature and moisture conditions in the near-wall and bottom rock masses of an open pit mine in the cryolithic zone depending on the geometric dimensions of the open pit. A computer implementation of the task to forecast the moisture and thermal conditions of the near-wall and bottom rock masses of open pit mines in the cryolithic zone includes the development of a mathematical model of the heat exchange, filtration and moisture transfer, as well as solving the task using numerical methods and computer technologies. A 2D mathematical model of the heat and moisture transfer in the near-wall and bottom rock masses of an open pit mine in the cryolithic zone has been developed with account of moisture ingress, evaporation, migration, and phase transition. An important feature of this model is the absence of a clearly defined boundary between zones of complete and incomplete water saturation, which makes it applicable for analyzing complex geological environments. A computer software based on the developed mathematical model enables long-term forecasting and research into the characteristics of the thermal and moisture conditions in the near-wall and bottom rock masses of an open pit mine in the cryolithic zone depending on various natural and climatic conditions and the design parameters of the open pit mine. Test calculations were performed to assess the impact of the open pit geometric dimensions on the process of forming the moisture and thermal conditions of the near-wall and bottom rock masses of an open pit mine.
