| Abstract: | The 5-storeyed reinforced concrete frame building to be demolished in the transfer station of Heshan power plant is only 0.3m away from a fan house in western side,connected with a tool room in northern side and adjacent to an oil-storage necessary to be protected in southern side.The blasting cut was arranged on second floor and the blasting points on the end row of posts were risen to 0.5m over the roof of the fan house,avoiding the effect of the recoil on the fan house.Through pre-treatment,the building was separated from the tool room.An erected protection structure was used to resist the flying rocks,protecting the oil-storage.In this paper,selection of blasting cut height and parameters,pre-treatment,design of priming circuit and safety precaution measures were introduced. |
