摘　　要：针对深井复合顶板煤巷的典型围岩条件,通过相关的理论分析和数值模拟计算,提出了合理的组合锚杆支护方案,并进行了工业性试验及矿压观测分析,证明了组合锚杆支护技术能有效控制深部复合顶板回采巷道围岩变形,满足安全生产需求。为该类煤层巷道采用组合锚杆支护提供了参考和借鉴。Pointing to the typical surrounding rock of coal roadway with complex roof in deep mine, through numerical simulation and theory analysis, achieving rational combination bolts supporting way, and then industry experiment and mine pressure observation have been done, proving the support way is correct, long-term stability of the roadway has been achieved, which subsequently will make way for safe production of the coal mine. This engineering instance can be a valuable reference to support of similar coal roadways.
