摘要
矿柱的稳定性是影响矿山生产安全的重要因素。用现有的方法计算单个矿柱安全强度，并确定其破坏与否，难以正确反应存在多个矿柱的采场的整体安全性。文章从分形理论出发，建立了多矿柱采场项板受力模型以及矿柱破坏的分形树模型。通过对矿柱安全系数的分析计算，导出保证采场整体安全的矿柱安全系数，并进一步确定了矿柱的承载面积系数与开采深度之间的函数关系。研究结果对矿山设计、生产与安全具有十分重要的指导作用。
The stability of pillars is a very important factor to mining safety. Using current methods to calculate the single pillar＇s capability, in order to determine whether it will be broken or not, can not usually represent the precise situation of the whole mining stope. In this paper a load sharing model is built for the multi - pillars mining stope with a fractal patterns theory, an effective safety factor of pillars is introduced and the relationship between the pillar ＇ s loading section and the depth of mining is determained as well. The results obtained are very useful to mining design and mining safety.
