单条沿脉巷道通风网路炮烟运动分析及对策

针对山东省中小型黄金矿山存在的单条沿脉巷道通风问题，应用紊流变形理论和风速非均匀分布的规律分析爆破后有毒气体、粉尘的排除过程，论述一个中段中有一条沿脉巷道的通风网路所造成的污风串联，同时相关的阐述了凿岩、装运等作业产尘、除尘特点。通过进一步对这种通风网的讨论，提出了相应对策和措施。

Analysis of the Blasting Fume Movement in Single Strike-drive Ventilation Net and the Countermeasures

In view of the problems in the single strike drive ventilation net existing in the small and medium sized gold mines in Shandong province,the turbulent deformation theory and the law of ununiform distribution of air velocity are used to analyze the removal process of poisonous gas and dust and describe the polluted air serialization caused by only one strike drive ventilation net in middle mining section and the dust production and removal characteristics in drilling,loading and hauling.Based on the further discussion of this kind of ventilation net,countermeasures are suggested.
