Abstract:Rockburst is a kind of geological disaster attributed to dynamic instability. Based on the phenomena of both rock core disking and side wall scaling in cross-cut drift,which were found in the engineering geological drilling and the site investigation in Qilinchang Mining Area,Huize Lead-Zinc Mine,the basic patterns of rockburst in this mine are summed up,and the mechanism of rockburst is analyzed according to the results obtained from investigation and experiments. The study results provide an important basis for a reasonable selection of deep mining methods and the rockburst control.
