摘要(Abstract)：

介绍了不同抵抗线的单孔、单排孔爆破试验,采用摄影法分析爆堆块度的组成。试验块度分布符合R-R(Rosin-Rammler)分布模型,使用线性回归求出特征块度x0和均匀指数n。通过对分布参数的分析,揭示了一定地质条件下深孔台阶爆破抵抗线对破碎块度的影响规律,并对其应用进行了探讨。
In this paper,series of experiments of single hole and single row bench blasting with different burdens were designed and conducted.The fragment size distribution of the blasting muckpile was analyzed by using photograph method.Fragment size distribution of experiments accord with the R-R(Rosin-Rammler) distribution model,characteristic fragment size(x_0) and fragmentation gradient(n) were drawn by linear regression.Based on the analysis of distribution parameters,the correlation between burden and fragment size was revealed in deep hole bench blasting at a particular geology condition.The paper was concluded with the discussion on the application of this research.
