摘　　要：通过RMR和Q 2种岩体分级方法对程潮铁矿进行了岩体分级,将2种分级结果比较得出了综合的岩体分级结果,并将岩体分级结果应用到该矿的-430 m水平,以此绘制了-430 m水平的岩体分级区域图,为巷道支护方法的选择提供了有效参考。Chengchao iron mine is classified to different rock masses with the two kinds of rock mass classification method of RMR and Q. An integrated classification result was reached by comparing the two and the result was applied to -430 m level of the mine. A chart of -430 m level of rock mass classification was drawn. It provides references for the selection of tunnel support methods.
