Study on Smooth Blasting of Tunnel in Fault Formation
From the characteristics of rock damage, the mechanism of rock blasting into seam was discussed. Based on the joint mechanism of stress waves and explosive gases, the blasting method adopting slotted pipe charge structure in fault formation was studied, and the test results were used in Guanjiao tunnel of Qinghai-Tibet railway. The field tests show that the perimeter hole adopting slotted pipe charge structure improves the phenomenon of over-excavation in fault formation obviously.
