摘　　要：针对煤层间距较小采用连采工艺时下部工作面开采会由于顶板不稳定而导致巷道变形严重的问题,以601工作面为例在对其顶底板条件分析的基础上,提出了连采工艺巷道的支护原则,并对根据煤层间距不同提出了不同的支护方案;最后,分别通过锚索锚杆工作载荷和顶板、两帮围岩位移量的变化验证支护方案的有效性和可行性。In view of the problem that the lower working face will be seriously deformed due to the instability of the roof when the continuous mining technology is adopted when the coal seam spacing is small,taking 601 working face as an example,based on the analysis of its roof and floor conditions,this paper puts forward the support principles of the continuous mining technology roadway,and puts forward different support schemes according to the different coal seam spacing.Finally,the effectiveness and feasibility of the support plan were verified through the changes in the working load of anchor cables and anchor rods,as well as the displacement of the roof and surrounding rocks.
