全面法采场矿柱稳定性及影响因素敏感性分析

全面采矿法在采场中留下规则(方形、矩形或圆形)或不规则的矿柱作为永久支撑,不予回采。全面法矿柱的稳定性与采场结构参数密切相关,作为采场结构参数优化研究工作的前奏,有必要对全面法采场矿柱的稳定性及其影响因素的敏感性进行分析。本文利用南方某钨矿为工程背景,详细介绍了矿柱稳定性分析,进行了矿柱稳定性影响因素敏感性正交极差分析,最后对矿柱稳定性进行校核。研究方法及结论可以作为类似矿山设计的参考依据。

Stope Pillar Stability and Sensitivity Analysis of Effect Factors in Overall Mining Method

In overall mining method,regulars stope pillars(square,rectangular or round) or irregular pillars are left as a permanent support,not mining.The stope pillar stability is closely related with stope structural parameters.As the prelude of structure parameter optimization,the stability of stope pillar and its influencing factors sensitivity for overall mining method need to be analyzed.In this paper,a Wolfram mine in South as the engineering background,details of the pillar stability analysis are introduced,t...
