| Abstract: | This text has described the characteristic of the comples roof roadway, analyzed the mechanism of bolt and cable supporting, put forward adopting high-strength bolt to restrict the deformation of the surrounding rock, keep the surrounding rock steady, prevent comples roofs to destroy and voluntarily protect the surrounding rock, adopt the pre-tension cable to strengthen and suspend the unstable comples roof to the deeply stability rock stratum of the roof. The research results have already been applied to the project successfully. |
