摘　　要：复合顶板极软煤层巷道是围岩变形剧烈且顶板易冒落极难维护的巷道。分析该类巷道围岩破坏特点 ,提出运用注浆及锚杆支护控制巷道围岩稳定、加强顶板支护强度、充分利用围岩自身承载能力的支护原理 ,研究了合理的注浆、锚杆支护技术 ,包括高水速凝材料注浆加固两帮、顶板采用树脂全长锚固高强度锚杆和小孔径预应力锚索加强支护及两帮树脂加长锚固锚杆支护 ,并介绍一个工程实例。The bolting support principle is introduced to support roadways in extremely soft seam of coal mine with complex roof. The maintenance of surround rocks is controlled by reinforcing complex roof and two side walls. With an engineering example, a new kind of successful supporting technology is introduced. The roof is reinforced using full-column resin bonded high-strength bolts and pre-stressed anchor ware, and two side walls are strengthened using high water-coagulative material grouting.
