摘要(Abstract):

鉴于空气间隔装药预裂爆破合理空气比理论公式的复杂性,不便于推广应用,在分析现有预裂爆破线装药密度的经验公式基础上,完善并修正了线装药密度经验公式,并结合面装药密度的概念,得出了空气间隔装药预裂爆破合理空气比的半理论半经验公式,为爆破施工提供参考依据。
It is complex of the theoretical formula to calculate the air-decking ratio in air-decking presplitting blasting,so it is difficult to use.Basing on the existing empirical formula of line charge density in pre-splitting blasting,the existing empirical formula was improved and corrected,and combining with the concept of the surface charge density to obtain half theoretical and empirical formula of air-decking ratio in air-decking pre-splitting blasting,which could provide a reference for blasting construction.
