Abstract: In view of the complex environment ofdemolision project of Zhangze power plant workshops in Shanxi province andthe workshop's actual structure, we divide the workshop into threeexplosion areas and determine the overall directional demolition planwith one explosive initiation point, 12 sound elemental differencedelays, and a non-electrically strengthened dual-loop demolitionnetwork. The demolition vibration is calculated and verified. Effectivemeasures are taken to reduce the cave in distance. Good blasting results are obtained.
