摘　　要：通过矿压观测分析得到了回采巷道一次来压过后的收敛规律,利用Midas/GTS计算机数值模拟软件多次迭代计算,实现了有限元近似模拟大变形巷道的离散元问题,得到了二次来压过后回采巷道围岩的松动圈。并基于围岩松动圈理论对巷道进行了支护参数优化,为回采巷道支护提供可靠的理论依据和技术参考价值。The convergence law of gateway after the first pressure was obtained by mine pressure observation and analysis.By using the Midas / GTS numerical simulation software,the broken zone of gateway surrounding rock after the second pressure was acquired. Based on the theory of surrounding rock broken zone,support parameters of gateway are optimized. The research provides reliable theoretical foundation and valuable technical reference for gateway support.
