Analysis method of mine ventilation difficulty degree based on ventilation equivalent area

Analysis method of mine ventilation difficulty degree based on ventilation equivalent area

In view of problems that equivalent orifice commonly used in current mine ventilation difficulty degree evaluation cannot effectively reflect details of ventilation difficulty degree, and ventilation resistance measurement cannot well measure effect of complex ventilation system in parallel, an refi...
