白竹磷矿地下开采岩体移动变形分析

Analysis of displacement and deformation due to underground mining in Baizhu phosphorite mine

根据鄂西山区白竹磷矿地下开采工程实际情况,利用随机介质理论模型,对地下开采引起的地表移动变形进行了具体的计算分析。将理论结果与实测资料进行了对比,二者吻合,所获结果表明,本文提出的分析方法可用于分析山区厚磷矿层地下开采岩体移动变形问题。

Based on the mining condition of Baizhu mine in Exi mountainous areas, the stochastic medium theory is applied to analyze the rock mass displacement and deformation due to the underground mining of phosphorite ore deposit. A theoretical model for predicting rock mass displacement and deformation due to mining of thick phosphorite ore deposit are given in this paper based on the stochastic medium theory. And rock mass displacement and deformation are analyzed by using the model. The results have shown that the model is satisfactory and thus can be effectively used for predicting the rock mass deformation due to mining of thick phosphorite ore deposit in mountainous areas.
