| 1. | During recent years the seam cut has once again come into use . 近几年来,又再度使用了裂缝掏槽。 |
| 2. | If the charge used is too large, the rock can become sintered so that the cut used is a failure . 如装药量太大,岩石就会挤死,使掏槽失败。 |
| 3. | The norwegian cut can provide more dependable advance per round than the plough cut . 挪威掏槽与楔形掏槽相比,可以提供更可靠的每次爆破的进度。 |
| 4. | The loosening holes outside the plough cut are also drilled at an angle which improves the breakage possibility . 在楔形掏槽眼外侧的扩槽眼也要有角度以改善爆破效果。 |
