| Abstract: | The technology of excavating square shaft by pre-split blasting is introduced in this paper aiming at the difficulties for shape construction characteristics. How to set holes, control drilling precision and improve the structure of charge are introduced in detail. The blasting results showed that the wall of well is integrated and steady after excavation. |
