多井口多风机矿井反风的非稳定流动模拟

A transient-state simulation of reversed ventilation in mine with multi-intakes and fans

针对多井口多风机复杂通风系统反风决策的要求,利用计算机模拟,对多井口多风机矿井各种反风方式下风流流动的动态变化规律进行了分析研究,根据矿井风流非稳定流动计算数学模型的特点,并结合反风的具体要求编制了FORTRAN程序,用编写的程序对某矿各种组合形式的反风进行了模拟计算,结果与实测值吻合性较好。

In response to the needs for reversed ventilation decisionmaking in complex mine ventilation systems with multiintakes and fans, the transientstate ventilation process before approaching the steadystate condition has been analyzed and simulated for various operation combinations of reversing facilities. A FORTRAN program for dynamic simulation of reversed ventilation under various conditions was made and supported by relevant calculation examples. The results agree with practice.
