In this paper, the characteristics and laws of rockburst at headrace tunnels in Jinping II hydropower station are summarized basing on a mass of rockburst incidents recorded during tunneling, including the law of rockburst distribution with mileage, the way of failure of rock surrounding tunnel, the relationship of rockburst and distance, the laws of position of rockburst on cross section, etc。 According to relationship of the microseismic incidents and rockburst, the availability of application of microseismic monitoring technique to prediction of rockburst is argued, and the accuracy and reliability of it are proved。
