Abstract: Explosibility classification evaluation was done on rock mass of an open-pit mine by using the dynamic grading method, and the result was consistent to grading result based on attribute recognition model based on coefficient of entropy. While it is more simple and efficient for explosibility classification of rock mass by using the dynamic grading method, and it has good adaptability and objectivity.
