摘　　要：为了提高掘进进尺、加强顶板管理和提高巷道的安全程度,采用理论研究的方法,研究了锚杆支护参数设计、施工工艺及其与锚索合理匹配等技术难点问题,并提出了可行的解决方法,研究结果表明合理的参数设计、施工工艺和匹配关系可以改善巷道支护的安全程度,避免巷道冒顶事故的频繁发生,提高煤矿企业的技术经济效益。In order to improve the advanced rate of the gateway driving, to enhance the roof control and improve the safety of the gateway, with the theoretical research method, the paper studied the design of the bolt support parameters, the construction technique, the bolt with anehor rationally matched and other technical problems and also provided the feasible solution. The study results showed that the rational parameter design, construction teehnique and matching relationship could improve the safety of the gateway support, eliminate gateway roof failing accidents frequently occurred and to improve the technical and economical benefits of the mine enterprise.
