| Abstract: | Smooth blasting and shotcrete-bolt support is adopted in testing gallery, cement cartridge rock bolt support for local broken surrounding reck is selected as the supporting design for shotcrete-boh support with bar-mat reinforcement. The thickness of sprayed concrete is 70 mm, the reck bolt length is 1.8 m and the net dimension of reck bolt is 1.0 m × 1.0 m. Comparing the traditional support with the shotcrete-boh support, the latter has the outstanding advantages in economic benefit. |
