The article examines the issues of forecasting the hazard category of rocks based on the assessment of the stress state of the massif in specific conditions and is aimed at identifying areas of the gold ore deposit mountain range that are dangerous due to the stress state of the rock mass, in order to take measures in advance to prevent them. The method of acoustic emission of the forecasting and the methodology of measurements are substantiated.
Keywords
