Abstract: Through rock sampling at different geological regions in Jiaojia mine area of Jiaojia Gold Mine，laboratory experiments on rock mechanics are carried out to analyze the rock mechanics parameters.Then rocks are classified and contrasted by using the Q system classification method the RMR classification method and the BQ classification method to submit different rock mass grading.The stope safety production specification for different rocks is proposed，which has a positive effect on the production safety.

Key words: Mechanical experiments, Classification of rock masses, Stope specifications, Production safety
