摘要
实际上 ,矿井的风流状态受多种因素影响 ,金川公司二矿区井下风流就处于非定常状态 ,为了保证生产安全 ,控制风流状态 ,采取相应的通风措施 ,开设课题研究 ,建立了井巷内空气非定常流动能量方程和通风网络中非定常流动的数学模型。根据该模型可以模拟出矿井通风系统内非定常状态下任意时刻、任意位置通过风量。通过对金川公司二矿区井下机站风机开停和风门开关引起通风系统风流的非定常流动过程的数值模拟 ,得出了受其影响区域内风流状态的变化规律 ,并为其采取通风措施和控制风流状态 。
An unsteady airflow energy equation and a mathematical model of unsteady airflow are established for the ventilation network. This model could calculate the air quantity at any time in any position in mine ventilation systems. Unsteady airflow regularity in the mine ventilation system of Jinchuan 2# Mine is simulated by computer when the booster fans are in operation or not, and when the doors are opened or closed. The varying regularity of airflow states could be obtained in the affected district.
