摘要

采用相似材料试验和数值模拟相结合的方法，对锚网锚杆、U型钢和吸能支护条件下煤岩巷道冲击破坏过程进行研究，揭示了巷道与支护相互作用下的巷道冲击破坏机制。试验和数值计算研究结果表明，不同支护作用下巷道冲击破坏规律表现基本一致，在冲击载荷作用下，巷道顶板有明显下沉，底板出现起鼓现象，两边帮均向巷道内部方向发生弯曲变形，形成裂缝，进而扩展和贯通，并有抛出物冲入巷道内。根据模型试验和数值计算结果可知，不同支护条件下冲击破坏程度不同，吸能支护具有良好的缓冲和吸能特性，巷道变形较小，整体稳定性好，更适合于冲击地压巷道的支护。

Abstract

Adopting similar material simulation test and numerical simulation methods

the impact damage process of coal roadway under anchor bolt

U-steel and energy absorbing support are studied. The impact failure mechanism of roadway under interaction between coal and support is received. Similar material simulation and numerical results show that the impact damage laws under different support types are consistent with each other. Under impact loads

the roof sinks significant

the floor drum obvious

and the both sides have a large internal deformation; cracks expansion and through

even the coal thrown out. According to similar material simulation test and calculation results

it is shown that for different support types

different levels of impact damage

energy absorbing support has good cushioning and energy absorption characteristics

and advantages of small deformation and good stability. The test results also indicate that the energy absorbing support is better for rockburst roadway.
