摘要
本文根据所应用的不同理论和研究方法将现有的岩体爆破块度预测模型划分为三类,即应力波模型、分布函数模型和能量模型,简略介绍了模型建立的理论基础、研究条件以及最终结果。着重分析评价了各模型的特点,讨论提出了今后块度预测研究的问題和发展方向。
According to the applied theories and research methods, the present predicting models of fragment-size in rock mass blasting are classified into three types which are stress wave model distribution function model and energy model in this paper. The theoretical bases, research conditions and find results of all the predicting models are briefly introduced respectively first. And their characteristics are emphatically analysed and evaluated. Finally, authors discuss and propose the future questions and developing direction of the fragment—size predicting researches.
