EXPERIMENTAL INVESTIGATION ON THE TENSILE PROPERTIES OF WEAKLY CEMENTED SANDSTONE IN CHINA SHENDONG MINING AREA

ABSTRACT
To investigate the tensile properties of weakly cemented rock samples at Shendong Mining Area. Four common weakly cemented rocks are subjected to Brazilian Splitting Test, and both the acoustic emission signals and deformation field are monitored simultaneously. Thus, deformation and acoustic emission features were analyzed in different rock samples. Moreover, the relationship between the evolution of localization belt and acoustic emission features was identified. The results show that the samples displayed similar deformation features and that the evolution of R value is also basically consistent.
