2020/6/2Adequate control of methane is particularly acute in longwall operations using bleeder ventilation systems especially at the tailgate corner where methane accumulations are most likely to occur Also severe changes in atmospheric pressure may cause increased interaction with sealed areas of the mine that can overwhelm the normal ventilation system

Mine Ventilation Systems Ventilation is the control of air movement its amount and direction Although it contributes nothing directly to the production phase of an operation the lack of proper ventilation often will cause lower worker efficiency and decreased productivity increased

2015/3/1In coal mine ventilation design traditional conveyor systems have been placed in neutral airways to prevent the air used to ventilate these systems from actively ventilating the working faces However with increasing production rates leading to higher gas liberation and elevated airflows the conveyor entries have been used to provide fresh air to the working faces in conjunction with the
