DISCUSSION ON ROCKBURST INFLUENCED BY
REGIONAL STRESS FIELD IN CHINA
|
|
|
|
Abstract Rockburst influenced by the regional stress field is discussed. The correlation between rockburst and the solid tide has been discussed. The results show that rockburst occurrence has good correlation with the lunar solid tide. The correlation between rockburst and the regional natural earthquake has been analyzed；and it is found that the occurrence time of natural earthquake lags behind that of rockburst. The space distribution laws of rockburst have been considered. In the plane distribution，rockbursts are seen to locate in the earthquake-prone zones，and they are almost distributed in the earthquake zones of strong tectonic activities. There is a critical depth of rockburst occurrence in the depth distribution. The regional stress field is the one of important factors that affect rockburst occurrence.
