摘要:
为探索特大断面隧道分层开挖爆破烟尘的运移规律,采用现场实测分层开挖爆破前后粉尘质量浓度及CO体积分数变化,并基于实测数据建立烟尘扩散模型的方法,分析隧道分层开挖爆破后烟尘在空间内随时间的分布及演化特征。研究结果表明:隧道下层开挖爆破后烟尘迅速膨胀并快速充满断面空间,整体呈现“上移-扩散-沉降”的复合运移模式;对比风速0.47,1.54 m/s的2种工况,爆破后60 min时,后者人员呼吸带高度的粉尘平均质量浓度降低为前者工况的0.85倍,CO平均体积分数降低为前者的0.10倍。研究结果可为大断面隧道爆破施工的环境治理方案设计及优化提供数据支撑。
Abstract:
In order to investigate the migration law of dust and fume from layered excavation blasting in an extra-large cross-section tunnel,field measurements of dust mass concentration and CO volume fraction before and after layered excavation blasting were conducted.Based on the measured data,a dust and fume diffusion model was established to analyze the spatiotemporal distribution and evolution characteristics of dust and fume following blasting.The results indicate that after blasting in the lower layer,the dust and fume expand rapidly and quickly fill the entire cross-section,exhibiting a composite migration pattern characterized by “upward migration-diffusion-sedimentation”.Under two working conditions with wind speeds of 0.47 m/s and 1.54 m/s,60 minutes after blasting,the average dust mass concentration at the personnel breathing zone height under the latter condition decreased to 0.85 times that under the former,while the average CO volume fraction decreased to 0.10 times that under the former.The findings provide data support for the design and optimization of environmental control schemes for large cross-section tunnel blasting operations.
