Abstract:

Due to its advantages,such as well adaptability for various rocks,timely function of active prestress and high efficiency for assembling,split-set bolts supporting technique was widely applied in underground mining engineering.Combined with the production practice of Jiaojia gold mine,the radial and axial stress state in split-set bolt were analyzed based on RMR rockmass quality classification and elastic mechanism.Practice effects of the performance of split-set bolts for surrounding rock supporting in Sizhuang mining area has been introduced.It indicated that the split-set bolts played a good role in supporting gold rock,which could be a reference for other similar mine practices.

Key words: split-set bolt, supporting, fracture, Sizhuang mining area
