摘　　要：深井厚冲积层软岩巷道支护的出发点主要在于采用性能良好的锚固支护技术(高强度、高刚度、高预应力锚杆与锚索)进行及时支护,利用锚注支护技术提高围岩的整体性,为锚固性能的发挥奠定了基础。在赵楼煤矿不同类型巷道、硐室中,采用高强度高刚度高预应力锚网喷索和锚注为基础的支护体系,组成了"三高一及时"支护结构,在断面较大或极软弱部位辅以让压、局部关键部位加固等其他支护措施,获得了极好的稳定控制效果。The key to supporting soft rock roadway in deep thick alluvium is supporting timely with anchored supporting technology（anchored bolt and rope with high strength,high rigidity and high pre-stress） and applying grunting technology to improving integrity of surrounding rock ＂3-high＂ and timely supporting structure was used in different roadways and caverns and other supporting measures including yielding at large section or extremely-soft place and reinforcement at local key points in Zhaolou Colliery Application showed that the structure made excellent stability control effect.
