摘要
采用光面爆破掘进法,减小了对围岩的扰动和破坏,确保了围岩的完整性及自身的稳定性,与超前锚杆、喷锚网、U型钢金属架支护配合使用后,保证了矿块回采进路的稳定性,同时为安全生产打下了良好的基础。
Adopting smooth wall blasting in excavation can reduce the vibration and the fracture to the surrounding rock, also it can guarantee the surrounding rock＇s perfection and stability. Compared with rock bolting, shoterete and boh, and U shape steel rib support, it can ensure the stability of the stoping tunnel＇s block, at the same time, it can offer a good environment for the safety work.
