| 摘 要： | 文章分析了冲击矿压时程特性对巷道支护构件的特殊功能要求,提出了冲击-支护的3D特性匹配,要求支护构件必须同时具备高强度、大刚度和一定的柔度,比较了钢棚、锚杆支护对冲击矿压震动破坏过程的适应性差异,分析了锚固结构中锚杆的轴向变形对P波的适应性及锚固体横向约束对S波的抵抗,并对锚网支护吸能防冲能力进行了近似计算.研究表明,锚网支护是目前相对较能适应巷道冲击矿压震动破坏效应的支护形式,约可抵抗震级为2.6的冲击矿压.

| Abstract: | Analyzing the function requirement of the roadway supporting system adjusting to the specialty of rock burst,we proposed the 3D coupling character of rock burst-supporting system.Supporting system must have the characteristics of high strength,large stiffness,and certain flexibility.The difference of adjustment to rock burst between steel-canopy and bolting have been analyzed,such as axial deflection's adaptability to P-wave and transverse constraint's resistance to S-wave of bolt in anchor system.In additi... |
