摘要
通过对焦家金矿焦家矿区进行不同地质条件区域岩石取样,进行实验室岩石力学性质试验,分析岩石力学参数。通过采用Q系统分级法、RMR分级法和BQ分级法对矿岩体分级并进行对比,提交不同岩体分类分级,并提出在不同岩石条件下采场安全作业规格,对提高安全生产具有积极作用。
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.
