基于 Mathews 稳定图的采场暴露面积计算

摘要

以富全铁矿采场为依托，通过对该矿－320 m 中段采场的工程地质调查、矿岩力学试验，获取了矿山岩体工程质量的多种指标。应用 Q 分级和 RQD 指标分析，对采场岩体稳定性进行了分析评价，基于 Mathews 稳定图法分析出合理的采场暴露面积，从而对采场结构进行优化。%Based on the stope of Fuquan iron mine,multi-indicators of the quality of mine rock mass engineering by conducting geological investigation and ore-bearing rock mechanics test.The Q clas-sification and ROD indicator analysis methods are used to analyze and evaluate the stability of stope rock mass.The reasonable exposure area is obtained based on Mathews stability diagram analysis method so as to optimize the stope structure.
