中文摘要：
采用大型有限元分析软件——ANSYS对康家湾．矿深部难采矿体典型采场顶板的稳定性及其对采场围岩力学状态的影响进行数值模拟、非线性分析，对9种典型采场结构模型的模拟结果进行了比较分析，根据分析结果结合采掘效率和开采成本等因素确定了采场最优结构参数，并对当前采矿方案提出修正和调整建议，以便更清楚地掌握深部地压变化规律，有效地进行地压管理，实现深部破碎带矿体及顶板不稳固矿体的安全高效开采．
英文摘要：
The stability of common stope＇s roof in Kangjiawan mine, Hunan province, China, as well as, the influence of mining process on mechanical behavior of surrounding rock, was simulated by the finite element analysis software - ANSYS in the paper. Non - linear simulated results of nine stope models to give optimum stope sizes with high effectiveness and low cost. Correction measures of current mining techniques are also suggested according to simulation results, so that variation rules of deep ground pressure could be clarified and ore bodies under weak roof could be extracted effectively and safely.
