改造采区通风系统提高经济益

Transform Ventilation System in Mining Area and Enhance Economy Benefit

城子河煤矿立井东一采区原通风系统,通风阻力大,不利于采区正常回风,为提高通风能力,形成科学合理的通风系统,对城矿东一采区通风系统进行技术改造,降低通风阻力,增加经济效益。

The ventilation resistance of the original ventalation system in the No. 1 east tinning area oi me shaft of Chengziher Coal Mine is big, which is not favorable to the normal wind. For improving the ventilates ability and forming the reasonable science ventilation system transforms the raw ventilation system for reducing the ventilated resistance and increasing the economic efficiency.
