在发生突出事故后,可用如下方法加强巷道通风,增加并联风路的阻力(关闭风门、设置密闭)或者打开事先设在事故采区巷道中的风门以调节风量,调节主扇并将备用风扇并联工作。用上述增阻法加强通风的效果,与调节设施(风门、密闭)的安装地点、通风网路的复杂程度、调节设施阻力大小等有关。将调节设施安在距事故采区最近的并联风路里,可使风量增加20～35%。对于各别采区来说(图 а、б、в),最好是在两
In the event of a major accident, the following methods can be used to enhance the ventilation of the roadway, increase the resistance of the parallel airway (close the air damper and set airtightness), or open the air damper previously set in the accident roadway to adjust the air volume, adjust the main fan and connect the standby fan in parallel jobs. With the above method of increasing resistance ventilation to enhance the effect, and the regulatory facilities (throttle, airtight) installation site, the complexity of ventilation networks, regulating the size of the facility resistance and so on. Adjusting the facility to the nearest parallel air duct from the accident mining area can increase the air volume by 20-35%. For each mining area (Figure а, б, в), preferably in two
