【 摘 要 】

According to the requirements of ore mining, this paper comprehensively evaluates the quality of rock mass below 915m in a gold mine in northwest Jiaodong by rock mass engineering geological survey and comprehensive quality evaluation. The results show that the rock mass near the ore body or the F1 fault area is gradually deteriorated, and the rock mass of the ore body or the F1 fault is still poor. The RMR index of the rock mass is in the range of 35∼50, mostly the grade III poor rock mass.
