摘要
传统的硬岩支护理论和支护方法不能很好地满足矿井深部软岩巷道支护的需要。所以通过分析软岩支护中变形特点,对自稳平衡拱理论进行讨论,推导出力学平衡方程,又对常见的六类软岩支护方式进行分析评价。
The traditional hard rock support theory- and support method cannot well meet the needs of deep soft rock roadway support. By analyzing the characteristics of soft rock, the mechanical equilibrium equation of self-stable balanced arch was deduced, and six kinds of common soft rock support methods were analyzed and evaluated.
