ti = l(i,i-1)/Cpi, с,
где l(i,i-1) - расстояние между i-й и предыдущей группами зарядов, м;
Cpi - скорость распространения продольной волны между i-й и i-1-й группами зарядов в момент инициирования i-й группы зарядов, м/с.1. The method of blasting, including preliminary weakening of the rock mass by drilling additional blast holes, loading them with explosives and short-blast blasting with a certain delay, characterized in that the front of the ledge is oriented subparallel to the main axis of the anisotropy of the massif, it is divided into separate blasting blocks , they drill and blow odd blocks first, and then even blocks, while groups of borehole charges of odd blocks are blown in transverse rows, starting from the middle s of each block, the first to explode with a zero degree of deceleration, a group of charges on the central odd block, the subsequent groups of charges of odd blocks explode with a deceleration interval t i equal to
t i = l (i, i-1) / C pi , s,
where l (i, i-1) is the distance between the i-th and previous groups of charges, m;
C pi is the longitudinal wave propagation velocity between the i-th and i-1st groups of charges at the time of initiation of the i-th group of charges, m / s.
L = (0,5-0,8)Kпα(Q
где Кп - коэффициент свойств горных пород, м/кг1/3;
α - коэффициент условий взрывания;
Q1, Q2 - массы зарядов взрывчатого вещества во взрываемых в нечетных блоках группах зарядов, кг1/3.2. The method according to p. 1, characterized in that the length of the even blocks L is determined by the formula:
L = (0.5-0.8) K p α (Q
where K p - coefficient of rock properties, m / kg 1/3 ;
α is the coefficient of explosion conditions;
Q 1 , Q 2 - mass of explosive charges in groups of charges exploded in odd blocks, kg 1/3 .
