中文摘要:针对盐矿地下开采设计中矿柱宽度的选取问题开展研究。通过理论分析,推导得到了基于极限平衡法的矿柱极限宽度理论公式;通过引入安全系数,提供了一种能够服务于矿柱设计的矿柱宽度选取方程;结合具体工程,给出了一个合理的工程算例,明确了该设计方法的具体应用。研究结果表明,给出的开采矿柱设计的极限平衡法能够满足地下盐矿开采的设计需要,为类似工程设计提供有益参考。

The pillar design method in underground rock-salt mining based on limit equilibrium
Abstract:In view of the problem at selecting mining pillar width for underground rock-salt mining design. With theoretical analysis, the theory formula of pillar width limit was derived based on the limit equilibrium method. By bringing the factor of safety into the formula as mentioned above, a new design equation was provided for selecting the reasonable pillar width. Combined with specific engineering, a reasonable engineering example was given in this paper and made the application of the design method clearly. The results show that the given mining pillar design limit equilibrium method can meet the needs of the design in underground rock-salt mining, which is a reference for similar engineering design.
