| Abstract: | The grading of rock drillability is an important index for well organized production and efficient opera-tion in mines so that proper grading of rock drillability is in crying needs in open pit mining. Considering the compli-cated occurrences of Baayan-Obo west deposit and altered igneousrock, a long-range and representative sampling andphysical mechanics characteristic test are conducted, toge（her with a field test of cone drilling in different kinds of rocks. The results show that the rock drillability is closely related with the physical and mechanical property of rocks. |
