| Abstract: | A new view of using value A and B of rock as indications of rock drillability is put forward. The principle as well as methods of measurement for value A and B are researched. It is practicable to make bit formula using value A and B of rocks as guiding facts. |
| Keywords: | rock drillability grade value A of rock value B of rock |
