    Advances and prospects of stope stability evaluation methods in metal mines

    • 摘要:

      影响矿山采场稳定性的因素错综复杂,为了减少矿山采场开采过程中人为因素的影响,对矿山采场的稳定性进行分析评价是十分必要的。概述了金属矿山采场稳定性评价体系由依赖单一岩体质量评价指标到多指标定量定性分析的发展历程,总结了经典力学解析法与评价体系中应用较多的工程类比法、Mathews稳定图表法与国标评价法,介绍了数值模拟法、不确定理论法和神经网络法评价体系在金属矿山中的应用。根据目前各评价系统的应用情况,分析其存在的问题与不足。研究结果表明,在金属矿山中,各类评价体系均有其优势与不足,针对不同类别、不同大小的矿山应采用不同的评价体系进行分析评价。提出要借助现代计算机技术,实现基础数据的日常化快速采集与信息化管理,从而实现采场稳定性的快速连续评价,并且应根据深部岩体“三高一扰动”的恶劣赋存条件,探究适用于深部采场的稳定性评价体系。

       

      Abstract:

      The stability of mine stope could be effected by complex factors.In order to reduce the influence of anthropic factor in the mining process of mine stope,it is necessary to analyze and evaluate the stability of mine stope.Summarizes the development process of stope stability evaluation methods in metal mines from relying on single rock mass quality evaluation index to multi-index quantitative and qualitative analysis.Which includes the classical mechanics method,Mathews stability method and national standard evaluation method which are widely used in the evaluation system,and introduces the application of numerical simulation method,uncertainty theory method and neural network method in metal mines.According to the application of each evaluation system at present,the existing problems and shortcomings are analyzed.Moreover,research demonstrates that each evaluation system has advantages and disadvantages in metal mines,and different evaluation system should be adopted for different types and sizes of mines.Proposes to use modern computer technology to realize the daily rapid collection and information management of basic data,so as to realize the rapid and continuous evaluation of stope stability evaluation methods.According to the bad occurrence conditions of “three highs and one disturbance” of deep rock mass,the stability evaluation system applicable to deep stopes should be explored.
