Unloading deformations of surrounding rock in jointed roadways
Yantu gongcheng xuebaoThe rock mass in nature often develops joints of different scales under the action of long-term geological tectonic movement, and the stability of surrounding rock of roadways has a great relationship with the development of joints.
