摘要
本文采用动态分析法,分析了上行风流火灾中旁侧支路风流逆转的现象。首次提出了长度越大、初始风速越高的巷道越不易发生风流逆转的结论。从而突破了静态分析法的局限,加深了对矿火井灾风流紊乱现象的认识。该结论为选择最佳的避灾路线提供了新的依据。
n this paper, the dynamic method is used to analyse the flow reverse in bypass road during a fire in upward flow. A conclusion, which is that flow reverse will be retarded in a road with more length and higer initial flow rate, is first put forword. This conclusion breaks through the limitation of the static analysis method and deepens the understanding of the flow disorder during mine fire. Moreover, it provides a new basis for the selection of the optimum escape route.
