摘　　要：为了实现护顶措施控制下采场的结构参数优化,采用大型有限元分析软件——ANSYS对康家湾矿深部典型采场顶板的稳定性进行数值模拟、分析,根据结果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发展变化规律,有效进行地压管理,实现深部顶板不稳固矿体的安全开采。In order to realize the Mope structure parameter optimization under the top security measures control, the finite element analysis software——ANSYS was used to numerical simulate and analyse the typical deep mine stope stability of the plate items of Kangjiawan Mine, and some amendnlents and adjustments were given based on the results of the current mining, in order to have a clear grasp of the development of deep pressure, manner to pressure management effectively, and achieve deep roof of the unstable orebody mining safely.
