摘　　要：采用岩石力学有限插分数值模拟计算分析 ,揭示了程潮铁矿淹井后在支护状态下采准巷道围岩的应力、破坏区分布和位移变化等力学机理与基本特征 ,为现场支护设计提供了可靠的理论依据 。The development drifts in Chengchao Iron Mine once were flooded. The mechanical mechanism and fundamental characteristics of the wall rocks after flooding are discussed through finite numerical simulation in rock mechanics, with emphasis on stress change, failure area distribution and displacement variation of the wallrocks under support. Reliable theoretical basis is provided for in-situ support design which offers significant reference value.
