摘　　要：文章以平陆晋平煤业回采巷道底板泥岩易底鼓为工程背景,采用理论分析、数值模拟的方法,对比分析了注浆加固技术下的巷道围岩应力与塑性区分布规律,并对巷道围岩变化趋势进行了深刻探讨,验证了注浆加固技术对巷道围岩的显著控制效果。研究结果为平陆晋平煤业回采巷道底鼓治理提供了指导,同时为相似条件下煤层群开采提供了新思路。This paper takes floor mudstone easy heave of Pinglu Jinping Coal Industry Mining Roadway as the engineering background,uses the theory of theoretical analysis and numerical simulation to analyze the stress distribution and plasticity distribution of roadway surrounding rock,and the trend of change roadway surround-ing rock has been deeply explored to verify the significant control effect of grouting reinforcement technology.The results of the study provide guidance for the floor heave control of the mining roadway in Jinping Coal In-dustry,and at the same time provide new thoughts for coal seam group's mining under similar conditions.
