The control rock blasting system, and in particular, it is possible to adjust the precision disparity by controlling the detonation parallax of the delayed primer loaded in the cardiac hole, the heart enlargement hole, and the outer hole in multiple stages. In order to improve the construction work efficiency, the drilling step of drilling a deep hole, a deep hole enlarged hole and an outer hole to a predetermined depth of a predetermined form, and the explosive charge loading step of filling the delayed primer and explosives in the drilled ball, and In the blasting method consisting of a detonation step for detonating the loaded delayed primers, the cardiac cavity has a 20 to 20 ms detonation interval Load the primers with explosives and load the delayed primers with the explosive time interval of 100-500ms in the cardiac augmentation hole and the outer cavity together with the explosives to set a constant delay time for each circuit through the circuit configuration in the multistage blasting machine. It is characterized by blasting by adjusting to have a proper parallax.
