人们研究了能调节岩石破碎程度的柱状药包的结构。采用单个连续的柱状药包爆破时,爆破岩块的平均块度(x)=α_1/q(1/2),而采用一组柱状药包时则为(x)=α_1/q(1/2)+α_2/q,式中:α_1、α_2—表征爆破条件的函数,q—炸药单耗。综合这些公式可导出裂隙岩体中α_1、α_2与节理块平均尺寸x_o的关系 People have studied the structure of columnar kits that can adjust the degree of rock fragmentation. The average block size (x) = α_1 / q (1/2) for a single continuous cartridge burst is (x) = α_1 / q (1 / q) 2) + α_2 / q, where: α_1, α_2 - function of blasting conditions, q - explosive unit consumption. Combining these formulas, we can derive the relationship between α_1, α_2 and average size x_o of joint in fractured rock mass
