摘　　要：以江西新余石竹山—樟木桥矿区硅灰石开采为例,利用FLAC^(3D)软件模拟硅灰石开采过程中的围岩变形破坏特征,根据开采过程中围岩应力,塑性变形破坏规律的模拟结果,提出巷道和采场支护的合理方案,以预防硅灰石开采时引起垮塌、突水等地质灾害,保障矿产资源安全高效的开采。Taking the mining of wollastonite in Zhangmuqiao mining area,XinYu,JiangXi province as an example,using FLAC^3D software to simulate the deformation and failure characteristic of surrounding rock in the process of the mining of wollastonit,the paper proposed reasonable plan of the roadway and stope support on the basis of simulation results of the surrounding rock stress and plastic distortion damage law in the mining,which can prevent the geological hazards such as collapse and water inrush during the mining of wollastonite,and guarantee safe and effective mining of the mineral resources.
