摘要
唐钢石人沟铁矿目前处于露天转地下开采过渡期,亟需确定合理的地下采场结构参数.本文首先在岩石力学试验的基础上估算了岩体力学参数,采用三维有限元数值模拟方法对采场结构进行了研究,得出了地下开采时不同采场结构参数下采场的应力和应变情况,并以此为依据对其稳定性进行了分析,最终确定了最优方案,确定了石人沟北区合理的采场结构参数.
At present,Shirengou iron mine is experiencing transition to underground mining from open cast mining.To make use of these underground mineral resources effectively and safely,the reasonable structure parameters of the stope need to be determined urgently.Based on the analysis of engineering geology and current situation of Shirengou iron mine,this paper estimates parameters of rock mass and uses the three-dimensional numerical simulation methods to investigate the stope structure,and consequently gets the distribution of stress and strain of side and slope,which can be used to judge its stability.Through the comprehensive evaluation,the optimal project and reasonable stope structure parameters have also been acquired.
