增阻法改变进回风风门压力稳定矿井通风系统

Increases the resistance method to change into the return air inlet pressure stability of mine ventilation system

介绍了马脊梁矿石炭二叠纪回风斜井与胶带斜井贯通后,污风出现逆转,造成矿井西部区域大面积串联,通过测压,改变局部地段的压能,前移高压能点,由高压区的正压变为负压,延长负压区域,稳定通风系统,增强了矿井通风系统抗灾变能力。

Connecting return air inclined shaft and belt inclined shaft in Majiliang Carboniferous Permian caused the ventilation lines connection and the polluted air reversed in western region, by pressure testing, can change the local area pressure energy, the high-pressure energy point move forward, from the high pressure region of positive pressure, and extend the negative pressure, stabilize the ventilation system,and enhance the disaster resistance capability of mine ventilation system.
