摘　　要：本文提出了在多边界爆破体系中的上破坏作用半径的统一计算公式.它既适用于松动爆破、抛坍爆破,也适用于抛掷爆破,其中的崩塌系数A是作为岩体坚固系数f值的函数而提出的本文的公式兼容了国外这方面的计算公式,并使该公式的物理概念更为明确.In this paper, a formula for calculating the top radius of blast funnel in a mult-boundary blasting system is presented, in which the blast collapsibility coefficient was expressed as function of the rock solidarity coefficient. This formula can be applied to flexible blast, throw-slide blast and throw blast as well and is compatible with similar formulae published at home and abroad but the former is more definite in physical meaning.
