充填工作面上覆岩层运移规律数值模拟分析

Upper Overlying Strata Migration Regularity Numerical Simulation Analysis on the Filling Working Face

为了取得邢台矿7623充填工作面开采的充填效果,通过采用UDEC离散元分析软件,模拟分析不同等价采高充填开采时上覆岩层运移特征,得到7623充填工作面上覆岩层运移弯曲下沉及地表变形规律和充填效果。该技术的成功应用,为存在类似问题的充填工作面提供了可借鉴的经验。

In order to get Xingtai 7623filling working face filling effect,through the use of UDEC discrete element analysis software,simulation analysis of upper overlying strata migration regularity underdifferent equivalence mining height backfill mining,upper overlying strata migration bending subsidence and surface deformation law and filling effect analysis.The successful appclication of the technology provided reference for similar filling working face.
