摘　　要：针对目前研究矿井通风系统可靠性时,主要的研究参数是风量,即认为风量不失效则风路不失效的问题。提出了考虑风量、粉尘浓度、温度、有毒有害气体浓度指标的风路可靠度的定义,即研究可靠度时,既要考虑风流的数量,又要考虑风流的质量,这在矿井火灾时期尤为重要。根据风量动态监测结果,利用概率论、数理统计和可靠性原理的知识,提出了风路可靠度的理论计算数学模型,该模型的建立对矿井通风系统可靠性研究具有重大的意义。In view of the problem that at present, while studying the reliability of mine ventilation system, the main study parameter is air quantity, namely considering that airway does not fail so the air quantity of the airway will not fail. In the paper, considering air quantity, dust concentration, temperature and the concentration of poisonous and harmful gas, a new definition of airway reliability is put forward, namely while studying reliability, the quantity and quality of airflow should be taken into account, and this is especially important during mine fire. According to the real-time monitoring result, by using probability theory, mathematical statistics and reliability principle, a theoretical computing mathematical model for reliability is put forward. And the model is important to the reliability of mine ventilation system.
