西三回风立井主扇启用后降阻技术

Resistance reduction technology by using the main fan of West third return air shaft

马脊梁煤矿西三回风立井主要通风机启用后石炭系通风阻力大,不利于盘区正常回风及主要通风机的正常运转,为形成科学合理的通风系统,对西三回风立井主要通风机担负区域进行了全开路的调风及补掘回风巷,降低了矿井通风阻力,增强了矿井通风系统抗灾变能力。

After the use of the main fan of West third return air shaft in Majiliang Coal Mine, the ventilation resistance of the Carboniferous is large, and is not conducive to the normal ventilation of the panel and the normal operation of the main ventilator, to form the scientific and reasonable ventilation system, by adjusting air and supplementary extracting the return air roadway in the area undertaken by the main fan of West third return air shaft, reducing mine ventilation resistance, enhance the disaster resistance capability of mine ventilation system.
