张集煤矿反风时风流紊乱的原因分析及防治措施

为了解决张集煤矿反风时主要进风巷风流不反向的问题，利用风压平衡定律和通风能量方程对其通风系统进行分析，推导出风流不反向的判别式；利用现场实测数据对该判别式进行验证，结果表明判别式正确可用。结合风流不反向判别式和现场实际情况，提出防治反风时风流不反向的措施，确保了矿井通风系统的稳定性，提高了煤矿的抗灾能力。

Reasons and Preventive Measures of the Disordered Air Flow During the Anti-wind Time of Zhangji Coal Mine

In order to solve the problem that the ventilation was not reverse when the air was inverted in main air-intake roadway of Zhangji coal mine, the law of air pressure balance and the ventilation energy equation was used to analyze the ventilation system, and derive discriminant of the air disorder. The practical measured data was used to verifier the discriminant, and the results showed that it was correct.Combining the discriminant and the practical situation, the measure was provided to prevent the ventilation not reverse, to ensure stability of the mine ventilation system and improve its ability of fighting against disaster.
