喷雾降尘作业对掘进工作面空气湿度分布的影响

Infection of spray to reduce dust on humidity distribution of air in heading face

喷雾降尘是掘进工作面目前广泛采用的防尘措施之一 .结合压入式通风掘进工作面风流流场结构特点 ,探讨掘进工作面喷雾降尘对工作面 3区空气湿度分布的影响 ,建立了 3区湿度计算模型 ,得出了压入式通风掘进工作面 3区湿度分布不均匀的规律 ,为进一步研究通风过程中掘进工作面空气湿度的分布 ,正确评价掘进工作面作业环境及防尘措施 ,提供了新的理论参考依据 .图 1,参

The spraying to reduce is one of dust-proof measure which universally is used in the heading face at present. Recourding to the character of air current field in the heading face with forced ventilation, infection of spray to reduce dust on the air humidity distribution in three regions of the face is studied in this paper and the calculating model of the humidity of air is established, the regularity of air humidity distributing differently in the three regions is discovered. The results offer a new theory basis for the study on the distribution of the air humidity in the heading face during the forced ventilation processes, and accurately estimating work condition in the face and the dust-proof measure.1fig.,6refs.
