The mothed for calculating RQD is gived basied on the scanline survey. The rock mass in BAINAIMIAO COPPER MINE is classified according to the CSIR classification, so that there is the basis as stablity analyse.

• 用结构面间距的密度函数计算岩体质量指标RQD（RockQualityDesignation）值的具体方法及CSIR分类法对白乃庙铜矿的岩体进行了分类，为今后稳定性分析奠定了基础。
