The Loosen Circle Radius Based on the Theory of Damage Mechanics

Abstract:

After surrounding rock is disturbed by some damage form a loosen circle in surrounding rocks of a roadway, in order to solving the range of loosen circle, mechanical mechanism of loosen circle was discussed on the basis of damage mechanics and loosen circle radius calculation formula proposed. This work has some certain reference for roadway support design.
