Abstract The use of block caving to mine ores and rocks of kimberlite deposits in Yakutia (Udachnaya, Yubileynaya Mir pipes) will ensure high economic efficiency and productivity, reduce damage to diamond crystals due to non-explosive technology of mining. At the same time, block caving creates high technological risks associated with the essence of the technique itself, as well as the mining, engineering and geological specifics of kimberlite deposits. To ensure the effectiveness of the block caving method and planned progression of block caving, it is necessary to assess the influence of technological risk factors at the stage when caving parameters are determined to reduce the consequences during the whole life cycle of the mine.
