摘要

收起

采用爆炸力学、岩石断裂动力学对3种切缝药包进行理论分析表明，复合型切缝药包在切缝方向的剪应力是常规切缝药包的1.59倍左右；采用有限元软件ANSYS10.0/LS-DYNA对其进行数值模拟实验，通过对比3种装药结构的爆炸效果，表明复合型切缝药包在切缝方向的聚能效应最佳；通过对比复合型切缝药包切缝方向和垂直切缝方向的等效塑性应变，得出切缝方向塑性应变峰值是垂直切缝方向的2.93倍左右；通过对比远区围岩压力，得出复合型切缝药包在远区形成的爆炸压力最小，对围岩的损伤程度最小，能量利用最充分。

According to the theries of explosion mechanics and rock fracture dynamics mechanics, we found that the slits location shear stress of the complex ligamented charge holders is about 1.59 times of that of the conventional ligamented charge holders. The finite element software ANSYS10.0/LS-DYNA was employed to numerically compare the blasting effects of three kinds of seam cartridge, and it was found that the blasting effect of the complex ligamented charge holders is the best. Through comparing the effective plastic strain in the slits direction and vertical slits direction of the complex ligamented charge holders, we obtained that the effective plastic strain is the slits direction is 2.93 times of that in the vertical slits direction. After companing the pressure of surrounding rock in the far zone, we observed that the blasting pressure in the far zone of the complex ligamented charge holders is the lowest, which may lead to the minimum degree of injury to the surrounding rock and full use of the energy.
