摘要： PURPOSE: An accurate blasting method of using a vibration control is provided to smoothly blast successively a blasting hole interval, a blasting porous dehiscence interval, and a block interval by selecting propriety time according to a quality and a kind of a rock. CONSTITUTION: An accurate blasting method of using a vibration control comprises the following steps: a blasting object ground is punched; a different delay time is given to a blasting hole interval which is successively blasted; a delay time is determined in consideration of a kind of rock and a quality of rock; and the delay time exceeds 8ms. The delay time of a blasting hole interval in a same blasting porous dehiscence is calculated with a following equation. D_hth=A×S in the formula above, the delay time(ms) of a blasting hole interval in a same blasting porous dehiscence is defined as D_hth. A gap(m) of a blasting hole interval in a same blasting porous dehiscence is defined as S. A is a constant determined according to a rock kind of a blasting object ground. A has a value of 0 (ms/m) to 5 (ms/m). [Reference numerals] (AA) Firing time(ms); (BB) Blasting hole; (CC) Direction of movement
