Blasting demolition method for cyclone furnace

The invention relates to a demolition method for a high-gravity-center steel frame building, and particularly discloses a cyclone furnace blasting demolition method which comprises the following steps: (1) demolition of a non-bearing wall body of a concrete frame structure; (2) the concrete frame structure is divided into front-row stand columns and rear-row stand columns according to the dumping direction; (3) when the designed height of the front-row stand column notch is larger than that of the concrete frame structure, semi-cutting damage is conducted on a steel pipe inclined strut of the steel pipe frame structure on the upper portion of the concrete frame structure; (4) blast holes are drilled in the notch design range of the stand column and the blasting points on the tie beam and filled with explosives, and the blasting unit consumption is controlled to be 1.0 Kg/m < 3 > or above; and (5) setting the span of the front-row upright post and the rear-row upright post to be Xm, setting the delay time of t
