PURPOSE: A blasting method using a blast pressure induction control device and a control device for blast pressure induction applied to the same are provided to secure smooth and clean blast surface and minimize vibration and noise by controlling the transfer path of blast pressure. CONSTITUTION: A blasting method using a blast pressure induction control device is as follows. Respective explosives(1) are loaded in a plurality of blast pressure shield covers(110) in which a blast pressure induction path is formed. The explosives are fixed by being wrapped with a connecting band(115). A coupling projection formed on a side of the blast pressure shield cover is fitted to a coupling groove of another blast pressure shield cover. The blast pressure shield covers are connected together in the longitudinal direction. A detonator lead connected to one explosive is exposed to the outside of a blast hole(2). The connected blast pressure shield covers are inserted in the blast hole to face a designed blast line(4). A packing material is filled in the blast hole. The detonator lead is connected to a lead wire and an explosive is blasted.
