摘　　要：根据峰峰矿区十几条煤巷锚杆支护实践 ,提出了一种用于板裂结构顶板的锚杆实用支护设计方法。锚杆的悬吊作用和兜吊作用是该方法的理论基础。给出了锚杆参数设计的主要公式。实践表明该方法具有简单、实用的优点。At the present, the design method of roof bolt support in mine seam roadway can be divided into three methods at home and broad. And they are a project analogy method, value calculation method and support mechanism calculation method. Base on the roof bolt support practices in dozen seam roadways in Fengfeng mining area, the paper provided a practical roof bolt support design method for the block breaking roof. The suspended function and net suspended function of the roof bolt are the theoretical base of the design method. The paper specially discussed the design principle and finalized the parameters of the roof bolt support. Finally the practical application of the method in Wannian Mine shown that the parameters of the roof bolt support made with this method were safe and practical.
