Abstract
While the construction of dismantling the old industrial complex and restoring the dismantled industrial site to its original natural environment the is underway. In this paper, we introduce a case of dismantling a turbine building which one of the a large steel frame structures in an old industrial complex by applying the progressive collapse method among the blasting demolition methods. We used a charge container that generates a metal jet to cut dismantling the turbine building. The thickness of the steel structure was adjusted to 30 mm or less by applying gouging, which was a method of digging deep grooves by gas and oxygen flames or arc thermal, in the part where the cutting thickness was thick in the blasting section. The total amount of charge used for the blasting of turbine building was 175 kg, 165 electronic detonators and 124 charge containers. As a result of the blasting demolition, the turbine building was collapsed precisely according to the estimated direction. The blasting demolition was completed without causing any damage to the surrounding facilities.
