针对软岩巷道支护困难的问题,根据预应力锚杆支护和锚注支护理论,提出应用预应力锚注支护技术控制软岩巷道的方法;运用数值模拟方法对无支护巷道、锚注支护巷道和预应力锚注支护巷道的控制效果进行对比,得出预应力锚注支护对软岩巷道的控制效果明显优于其他2种支护方式。 Aiming at the problem of soft rock roadway support difficulty, according to the theory of prestressed bolt support and anchor injection support, a method of controlling the soft rock roadway with prestressed anchor and grouting support technology is proposed. By using numerical simulation method, The comparison between the control effect of the anchor supporting roadway and the prestressed anchor supporting roadway shows that the control effect of the prestressed anchor and grouting support on the soft rock roadway is obviously better than the other two kinds of support ways.
