摘　　要：为深入系统地研究充填对围岩控制效果,本文以夏甸金矿七号矿区工程地质、开采技术条件为背景,采用三维非线性岩石力学数值计算方法,分析在无充填和有充填开采方案下,围岩应力及位移分布规律,为优化开采方法和技术参数,进行合理的采矿工程设计与安全生产管理提供理论基础和科学依据。研究成果在类似地质和开采条件下的推广与运用具有一定的参考价值和指导意义。For the sake of studying the effect of the surrouding rock eontroled by filling, this paper take the engineering geology and the condition of mining of No. 7 diggings in Xiadian gold mine as example, adopt three dimension non - linear rock mechanic numerical method, analyse the rule of the distribution of stress and displacement of surrounding rock under the different mining plans. This analysis method can provide rationale and scientific basis to the optimization of the mining metod and the technology parameter for the reasonable design of mining engineering and safe management of producing. The production of the paper have guiding significance in the mining engineering which have the similar geology and mining condition .
