摘　　要：通过对高家梁煤矿2-2中煤层20306工作面回撤过程分析,认为回撤通道支护质量与强度和贯通时工作面与通道顶板是否平整衔接对工作面采通、回撤时的通道顶板安全管理极为重要;末采时铺网、铺钢丝绳的质量对回撤支架时的顶板安全管理尤为重要。Through retracement analysis of 20306 working face in Gaojialiang coal mine 2-2 coal seam, think back to remove channel branch nursing quality and intensity and links up the roof of working face and the channel is smooth connection of working face mining through, the retracement channel roof safety management is extremely important; at the end of the production shop network, shop the quality of wire rope to withdraw support the roof safety management is particularly important.
