放顶煤开采对控制冲击地压的认识

Knowledge of sub level caving method to control underground impact pressure

    摘要
  • 摘要: 以实用采场矿压理论的成果为基础，着重分析了放顶煤开采条件下顶煤移动特征和支承压力分布规律。讨论了放顶煤开采的采场应力场的分布规律及其对冲击地压的控制作用。

     

    Abstract: Based on the practical theory of ground pressure, the characterisitcs of roof coal movement and the distribution law of abutment pressure are nainly analyzed. The distribution law of inner stress field and its effect on controlling underground impact pressure are discussed, when sub-level caving method is introduced.
