| Abstract: | 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. |
