Influencing factors of air curtain in cutting off roadway airflow
摘要
Abstract
In this paper, in view of the characteristics of mine air curtain in cutting off roadway airflow and the requirement of structural design, the main influencing factors of air curtain in controlling airflow were obtained by theoretical analysis on the flow model of single-machine recycling-type air curtain. Furthermore, the experimental model of air curtain to cut off roadway airflow was established by using similar principles. The experiment results show that the optimum angle of air curtain and optimum width of air supply outlet in the roadway are 30?and 8 cm, respectively. Finally, numerical simulation by FLUENT was conducted to verify the correctness of experiment results. The results can provide reliable theoretical guide to the structural design of mine air curtain in cutting off roadway airflow.关键词
