| Abstract: |
| Based on the result of study on linear charge, the paper discussed some ideas of design of chamber blasting employed in the second blasting engineering in Shougang Group. The blasting, considering the fact that the rock is severely racked and that the terrain varies a lot with multiple frees surfaces hill body, employed double layers and linear charge combining with centralized charge in the blasting device. And moreover, in this blasting, the relative bigger cavity radio in the area with small burden was designed in order to control the flyrock. The blasting was a successful one with the blasting vibration controlled within the limitation of blasting safety criterion. |
