| 摘 要： | 为初步探讨瓦斯压力对煤体爆破过程的影响,运用ANSYS/LS-DYNA软件对含瓦斯压力的煤体爆破过程进行数值模拟研究,分析比较了瓦斯压力的存在与否对爆炸应力波的影响,得出了瓦斯压力对煤体的爆破起积极作用。数值模拟结果表明,存在瓦斯压力的煤体爆破是爆炸应力波、爆生气体和瓦斯压力共同作用的结果。

| Abstract: | For preliminary study on gas pressure's influence on the process of coal rock blasting,a numerical simulation is carried out on the coal rock blasting process with the gas pressure using the ANSYS/LS-DYNA software.Whether the existence of gas pressure will influence the stress waves of blasting is analyzed and compared,and it's concluded that gas pressure plays an active role in coal rock blasting.Numerical simulation results show that coal rock blasting with the gas pressure is the coaction results of blas... |
