CHARACTERISTICS AND MECHANISMS OF ROCKBURST IN A DEEP MINE IN CHINA
The Huize Lead & Zinc mine is a deep km mine in Yunan chihong Zn & Ge Co.,LTD. in China with mining of the eighth orebody. The basic problems of this deep hard rock mine were high underground stress and development of the fault structure. After summarizing the geological conditions of this mine, the characteristics of rockburst such as rock core disking and rock formation spalhng were described and the basic rules of rockburst were elucidated by the field investigation. The rockburst types and intensity classifications were progressed to the surrounding rock of eighth orebody, and the medium to intense rockburst trend was defined for 1451m to 1261m levels in the eighth orebody. The influencing factors of rockburst including the initial rock stress, geological structure and mining depth were considered for analysis for causes and mechanisms of rockburst in this mine.
