Abstract: The article addresses the issue of gas-dynamic phenomena that take place during mining operations in the host rocks of the 'International' kimberlite pipe. The reasons causing gas-dynamic phenomena are reviewed, an analysis of geological and technological features is provided, an assessment of the geomechanical conditions of occurrence of the gas-dynamic phenomena is carried out. Basic methods of forecasting (based on the initial maximum gas seepage rate) and prevention (advanced shot-firing) of gasdynamic phenomena are currently used in conditions of the deposit. Application of these methods has made a significant contribution to the efforts of the mine personnel to control the gas-dynamic phenomena, and it also helped to gain an insight into the processes in progress. However, rock and gas outbursts continue to occur in the field under various conditions, including the conditions of the peripheral shot-firing, which makes finding further solutions a topical issue. The data presented in the article are a prerequisite for the theoretical development for modeling of gas-dynamic processes that take place during mining operations in the host rocks of a diamond kimberlite pipe.
Keywords: gas-dynamic process, host rocks, mining of diamond deposits, geomechanical environment, gas-dynamic characteristics
