| 摘 要： | 鄂西九女磷矿矿区地形条件复杂,由于开采后留下大面积空场,地压活动明显.根据其开采的实际情况,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,判断磷矿山体在开采过程中是否稳定,从而控制因采矿而诱发的山体失稳,保证矿山安全.

| Abstract: | Jiunv phosphate mining area located in western Hubei is in the complex terrain conditions.Because of the existence of large mined-out area,ground pressure performs activity.Based on the mining conditions of Jiunv phosphate deposit in mountainous areas,the stochastic medium theory is applied to analyze the rock mass displacement and deformation due to the underground mining of phosphate ore deposit.Determine whether the phosphate deposit is stable or not in the exploitation to control the rockmass instabilit... |
