摘要:
为了进一步探索爆破烟尘扩散规律，以及环境评估与预测的需要，在宏观角度上，运用箱模型云团扩散理论，对爆破云团的模型适用性进行了探讨，建立了爆破云团扩散控制微分方程。对某次工程爆破进行数值模拟，得到了爆破云团半径、云团高度和空气卷吸量随时间的变化关系曲线图。针对数值模拟结果与试验实测值之间存在的偏差进行了分析，结果表明，采用该方法进行爆破云团瞬时扩散模拟是可行的。
Abstract:
In order to further explore the diffusion law of blasting dust, and meet the need for environmental assessment and prediction, on a macro perspective, the applicability of the model for blasting cloud was discussed, and the differential equation controlling blasting cloud diffusion was established using the cloud diffusion theory of box model. The numerical simulation was conducted on an engineering blasting case, and the graphs were obtained about the blasting cloud radius, cloud height and air entrainment over time. The difference between simulation results and the experimental measured values was analyzed, and the results showed that this method is feasible for blasting cloud instantaneous dispersion simulation.
