摘　　要：论述了复合顶板巷道的特征,分析了复合顶板巷道支护机理,提出了采用高强锚杆限制围岩变形,保持围岩稳定,阻止复合顶板离层破坏,主动支护围岩;采用预应力锚索加强顶板支护,将不稳定的复合顶板悬吊到顶板深部稳定岩层中。研究成果已成功地应用于工程实践。This text has described the characteristic of the comples roof roadway, analyzed the mechanism of bolt and cable supporting, put forward adopting high-strength bolt to restrict the deformation of the surrounding rock, keep the surrounding rock steady, prevent comples roofs to destroy and voluntarily protect the surrounding rock, adopt the pre-tension cable to strengthen and suspend the unstable comples roof to the deeply stability rock stratum of the roof. The research results have already been applied to the project successfully.
