摘要
以河北滦县高官营铁矿典型矿段采场为工程背景,采用有限元理论建立了采场稳定性分析的三维有限元模型,运用MIDAS/GTS大型有限元分析软件,分析了采场设计参数和充填料配比给定下条件下采场水平和垂直关联影响及采场开挖与充填过程对地表的影响,得出了采场间水平和垂直位移、应力、应变的关联规律。
Taking the ore stope of typical ore section in Gaoguanying Iron Mine in Luan County,Hebei as engineering background,3D finite element model of stope stability analysis was established by using the finite element theory and design parameters of stope,interrelated influence of horizontal and vertical stope when filling materials ratio was given as well as and influence of stope excavation and filling process on the surface were analyzed using MIDAS/GTS finite element analysis software to obtain the interrelated rule of horizontal and vertical displacement,stress and strain of stopes.
