结合矿山的采矿方法及矿体赋存特征,采用FLAC3D数值模拟软件,建立了三维数值模型,对矿体在大体积充填体下的回采顺序进行了模拟研究,根据计算结果,从应力、位移及塑性区3个方面对不同的方案进行了比较分析,进而确定从中间向两翼的回采顺序为最优回采顺序,并针对矿山在未来开采中可能存在的问题提出了合理建议,分析结果对矿山的安全生产有重要的参考价值。
According to the mining method and ore deposit characteristics of the mine, the numerical simulation software FLAC3D was used to establish the three-dimensional numerical model. The mining sequence of the ore body under the large volume filling body was simulated. According to the calculation results, Plastic zone three aspects of the different programs were analyzed and compared to determine the order from the middle to the two wings for the optimal recovery sequence, and for the mine in the future mining problems that may exist reasonable suggestions, analysis of the results of the mine Safety production has important reference value.
