摘要：In rock mechanics laboratory experiments, single-component acoustic emission sensors are commonly employed to monitor the failure process of rock, and from which basic information such as fracture types and location can be extracted. However, the spatial information of particle vibration is usually missing, and also the polarization of single-component signal cannot be analyzed. All these render it difficult to make comprehensive analyses of acoustic emission waveforms and thus hinder the understanding of the mechanical properties of rupture sources. Since polarization analysis of data from three-component sensors can enhance the classification of multiple coupling waveforms, it is of great significance to investigate their applicability in acoustic emission analysis of fracture propagation in rock failure experiments. In this paper, we use a new type of three-component sensors in acoustic emission monitoring. Our results show that it provides more detailed information for understanding the dynamic fracture propagation in tight reservoir rocks. ? 2021 ARMA, American Rock Mechanics Association
