| 摘 要： | The fact of tunnel smooth blasting is those reduce over break and minimize fracturing of the rock at the boundary of an excavation. The select ruler and assured method of smooth blasting parameter are discussed, and the quality check standard of the smooth blasting, based on the under and over-break (5~15 mm), the circumferential hole mark ratio (>50%) and rock fragment, are found. A good benefit is gotten as these used in one tunnel.

| Abstract: | The fact of tunnel smooth blasting is those reduce over break and minimize fracturing of the rock at the boundary of an excavation. The select ruler and assured method of smooth blasting parameter are discussed, and the quality check standard of the smooth blasting, based on the under and over-break (5~15 mm), the circumferential hole mark ratio (>50%) and rock fragment, are found. A good benefit is gotten as these used in one tunnel. |
