深部板状矿体走向稳定矿柱和保护矿柱设计指南

Current position of strike stabilising pillar and bracket pillar design-Guidelines for deep level tabular orebodies

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 paper summarises the work done on strike stabilising pillars and bracket pillars as regiona1 support metheds in the deep level gold mines- The most important facts regarding pillar design are firstly that the criteria used by the industry to date have in general not led to satisfactory results in all cases,and second1y that each pillar is unique in its own setting,and therefore not amenable to global design criteria. The pillar design approaches for strike stabi1ising pil1ars and bracket piIlars proposed in this paper take these facts into account.
