Received: March 17, 2017 Revised: July 25, 2017 Accepted: August 18, 2017 Abstract: Introduction: For technical renovation of the thermal plant, one frame structure workshop of 50,000 m construction area and one reinforcement concrete chimney of 150m height shall be demolished by blasting in the same time. The engineering environment is very complicated and the accommodation space for the structures collapse is limited. Therefore, the collapse sequence, direction, scope of the structures must be accurately controlled to ensure the safe operation of the adjacent generator unit and transformer station.
