For utilization a geothermal energy and mining of a shale gas, hydrofracturing technology become important. In this study, in-situ hydraulic fracturing experiment and AE measurement at Mizunami URL was carried out to examine a break mechanism by hydraulic fracturing. The results suggested that AE with shear mechanism at first breakdown is dominated and AE with tension mechanism is generated at new fracturing.
