摘　　要：分析了深井厚复合顶板采空区上方煤层巷道的支护难点和特点,提出了围岩强化控制技术和此类巷道的锚杆支护方案,介绍了应用于淮南某矿深井厚复合顶板采空区上方煤巷锚杆支护的成功经验。实践证明,高预应力高强锚杆组合的围岩强化控制技术是控制深井厚复合顶板采空区上方煤巷围岩变形的有效方法。This paper put forward strengthening control technology of surrounding rock and anchored bolt supporting project by analyzing supporting difficulty and characteristic of deep coal roadway with thick combined roof above gob.It introduced successful experience of applying bolt supporting in deep coal roadway above gob in Huainan.Practice showed that high pre-stress anchored bolt with high strength was effective method for controlling deformation of deep coal roadway with combined roof above gob.
