| 摘 要： | 通过分析矿井火灾时期风流特点,即矿井火灾时期将产生大量的高温烟雾,指出在矿井火灾时期,如果仅仅某条风路的风量在规定范围内,并不能说明该条风路就是可靠的,还应强调该风路的粉尘浓度、温度、有毒有害气体浓度指标在规定范围内。提出了矿井火灾时期风路可靠度的理论计算式,分析了矿井火灾时期风路失效模式,提出了适合计算大型通风系统在火灾时期可靠度的“基于截断误差理论和网络简化技术的不交化最小路集算法”。

| Abstract: | By analyzing airflow characters during mine fire, namely there produced plenty of high temperature smoke , the air way could rot be considered reliable if only the ventilation amount is in the specified quantity. The emhasis is that the indexes such as dust concentration , temperature and concentration of poisonous and hazardous gases are in the specified ranges. A theoretical computation equation for determining air way reliability during mine fire is put forward. The failure trite of air way during mine fire is analyzed. A disjoint minimal path set algorithm based on network simplification techrology and truncation error theory for computing the reliability of large scale venfilation network during mine fire is put forward. |
