| 摘 要： | 文中采用理论分析结合数值模拟分析方法,对采用两种不同的支护方式下的围岩力学行为进行了研究。系统分析了不同支护前后围岩及充填体的应力、位移及塑性区的变化情况。结果表明:在深部顶板破碎煤层中,采用锚杆、锚索及金属网联合支护显著提高了围岩的强度和承载能力,有效地控制了深部巷道的损伤变形。采用本文支护方式及参数,使沿空留巷工业性试验取得成功。

| Abstract: | By means of numerical simulation software and theoretical research,deformation failure regularity of bolt support and bolt-cable support for deep cracked roadway is simulated.The stress,displacement and plastic zone of bolt support and bolt-cable support for deep cracked roadway is systematically analyzed.The research results indicate that the strength and bearing capacity of surrounding rock for bolt-cable roadway is greatly increased.So the deformation of deep cracked roadway is effectively controlled.So in the practice,we make good winning. |
