摘　　要：The destressing mechasm, rational parameters and adaptability of various kinds of destressing methods in roadway comers are analyzed in detril in thes paper. A new kind of destressing method by driving openings is proposed. The crux tha destressing openings control the deformation of surrounding rock of roadways, the affect to the destressing effect by the location and size of the destressing openings are analyzed by means of FEM. The results point out that the destressing openings can effectively reduce the floor heave nd side-to-side convergence of the roadway.protected. It has high destressing capacity and very extensive adaptability compared with the destressing methods near roadway contour, and it can be used to support the roadways in high-stressThe destressing mechasm, rational parameters and adaptability of various kinds of destressing methods in roadway comers are analyzed in detril in thes paper.
