Аннотация: Using a mathematical statistics approach, we review the procedure for type classification of acousticemission (AE) events into shear, tension, and collapse, proposed by Zang et al. (1998). The procedure isbased on counting the signs of first pulses of waves arriving at acoustic sensors and is widely used in rock physicsexperiments. Under the assumption that the determination errors of first-pulse signs at sensors have uniformand independent distribution , the statistical significance and power of the type separation test are evaluatedfor a given number of sensors used. We consider and compare three methods of the construction of astatistical test based on the P-value approach and symmetric and asymmetric statistical hypothesis tests.Considering the results of the statistical study, we propose some practical recommendations for selecting athreshold to classify AE event types in experimental studies.
