本文概述了黄金矿山深部开采采用走向稳定矿柱和保护矿柱作为区域支护方法的研究工作。关于矿柱设计最重要的事实是,第一,在很岁情况下,迄今采用的矿柱设计准则通常不会获得满意的结果;第二,每个矿柱自身的环境独特,因此不适合于普遍的设计准则。本文提出的走向稳定矿柱和保护矿柱设计方法考虑了这些情况。
This article summarizes the research work on the deep mining of gold mines using the stable pillar and the protective pillar as regional support methods. The most important facts about pillars design are, first, the pillars design guidelines used so far do not usually achieve satisfactory results at very old age; and second, because each pillars has a unique environment and is therefore not suitable for Universal design guidelines. These trends are taken into account in the design approaches to stable and protected pillars proposed in this paper.
