基于粗糙集规律分析的软岩矿山采场参数优化改进

Stope Parameter Optimization of Soft Rock Mine Based on Rough Set Law Analysis

针对矿山采场围岩破碎且含泥量大、易失稳破坏的情况,统计现有采场的采区暴露情况、地应力大小、围岩本身质量、采场维稳措施以及最终的破坏失稳等情况。将其作为条件属性,将最终的破坏失稳情况作为决策属性,对各属性离散及约简后,对采场失稳破坏规律进行了粗糙集规律分析。根据得到的失稳破坏规律,制定了新的采场参数及支护策略,实践证明,该方法科学有效,为矿山安全生产提供了有力指导。

In view of mine stope surrounding rock is broken and silt content is large,a condition prone to instability,make statistics on the exposure of existing stope,in-situ stress,surrounding rock's quality,stope stability maintenance measures and the final failure instability and so on.Treat it as a conditional attribute,the final failure instability is taken as the decision attribute,after discretization and reduction of each attribute,the rough set law of stope instability is analyzed.According to the instability failure law obtained,get new stope parameters and support strategy,practice has proved,this method is scientific and effective,it provides strong guidance for mine safety production.
