摘要
本文针对无底柱分段崩落法存在的问题 ,提出了崩落体的概念 ,通过试验得出了崩落体的形态 ,分析了影响崩落体形态的主要因素 ,阐述了放出体、松动体、崩落体三者的关系 ,就崩落体形态对放矿的影响进行了研究。并对今后无底柱分段崩落法降低损失贫化具有重要的指导意义。
With an eye to the problems facing Sublevel Caving Method Without Sill Pillar,this paper proposes the definition of caved are body,derives the form of caved ore body,analyzes the mian factors influencing the form of caved ore body,expatiates the relationship among drawn\|out ore body,loosened ore body and caved ore body and studies the impact of the form of caved ore body on ore drawing.The paper is of important instructive importance to reduce loss and depletion by sublevel caving method without sill pillar.
