| Abstract: | Base on the acoustic emission test on burnt rock loaded failure processing, the acoustic emission activities of the rock sample from the loading to failure were measured. The mechanics features and acoustic emission features of the whole processing of the burnt rock failure were obtained. The paper discussed the change law of the acoustic emission signals during the rock loaded failure, which would provide the theoretical references for the correct utilization of the acoustic emission information to monitor and measure the omen phenomenon. |
