摘要: RMR岩体分类和Q系统分类分析普得铁矿的整体稳定性,并用三维计算机数值模拟残矿回采过程中的应力分布情况。将以上三者得出的结果进行比较,得出普得铁矿残矿回采时岩体稳定性的综合评价,并对采场下一步生产回采做出合理建议。分析结果表明,RMRQ系统分类所得出的结论与普得铁矿实际开采稳定性情况相吻合。将以上2种评价方法与有限元数值模拟方法相结合,可以更准确地分析岩体的稳定性,对今后预测评价岩体稳定性工作发挥重要作用。

Abstract: RMRrock mass classification and  Q system classification were used to analyze the overall stability of Pude iron mine, and 3D FEM numerical simulation was applied to get the stress distribution during the residual ore mining. Comparing with the above three results, the comprehensive evaluation on the stability of rocks mass while mining residual ore for Pude iron mine was reached and some reasonable suggestions were made for the next production. The results showed that conclusions from  RMR and Q system classification were consistent with the actual exploitation stability. Combing the above two evaluation methods with FEM numerical simulation, rock mass stability can be analyzed more accurately, which plays an important role in predicting and evaluating rock mass stability in the future.
