摘要： 摘 要：针对郑州矿区三软煤层回采巷道矿压显现剧烈，围岩变形严重，需要多次扩修才能满足安全生产的实际情况，提出了先让压，再进行二次超前加固的支护原则，系统阐述了针对U型钢支护回采巷道的三类加固技术：“三节梁”加固法、辅助梁加固法、工字钢联合加固法，并对其优缺点及适用条件进行了探讨。现场实践表明：回采巷道超前加固技术的应用，降低了劳动强度及扩修投入，保证了安全生产。

Abstract: Abstract：In allusion to the practical situation that the mine strata pressure and surrounding rock deformation are serious in mining roadways of three-soft coal seam in Zheng Zhou mining area, repeatedly repair is required to meet the request of production safety. This paper proposes the principle that releasing the load firstly and than implementing secondary advance reinforcement. This paper systematically elaborates three types of reinforcement technology for mining roadways of U-steel，which is three beems reinforcement，assist beem reinforcement and I-beem combined support method，their advantages and disadvantages as well as applicable conditions are discussed. Practice shows that:the application of advance support and reinforcement technology can reduce the labor intensity and repair investment,the safety of product propress is ensured as well.
Key words: Keywords: advance support, mining roadway, U-steel support, Zheng Zhou mining area
