The principle of stability control of surrounding rock-bearing structures in high stress soft rock roadways

Through the description of the deformational features of the surrounding rock around high stress engineering soft rock roadways, the coupling stabilization principle of inner and outer structures in surrounding rock was put forward. The supporting principles of high stress engineering soft rock roadway (high resistance and yielding support, timely support, high strength and high stiffness supports) were proposed, which were applied in engineering practices, and obtained better achievements.
