摘要
Abstract
Sizhuang mining area of Jiaojia Gold Mine is gradually entering deep mining.At present,the stability of middle and deep stopes is poor.According to the influence of ground temperature,groundwater and ground stress in the actual engineering of Sizhuang mining area,the RMR classification is modified and improved,and the IRMR classification is proposed as the method of rock mass quality rating in Sizhuang mining area.The results show that most of the No.2 and No.7 orebodies in the main mining located at the depth of-280～-450 m have medium-stability III rock mass,and only part of the orebodies have poor stability IV rock mass.From the comparison of the results of RMR method and IRMR method,it can be found that most of the classification results are the same,only one project IRMR classification is 郁,the result is more reasonable.关键词
