煤矿通风系统的优化实现

Optimization of Ventilation System of Coal Mine

针对传统的煤矿通风系统在倒机过程中存在短暂停风的问题,提出了一种不停风倒机的煤矿通风系统优化方案。该方案在传统的煤矿通风系统的基础上,通过在两个风道上方各增加一个百叶窗式的平式对空风门来实现倒机过程中井下风量基本不变。实际应用验证了该方案的可行性与实用性。

In view of the problem of transient blowing-out in switchover process of ventilators of traditional ventilation system of coal mine,the paper proposed an optimization scheme of ventilation system of coal mine of switchover of ventilations without blowing-out.The scheme adds a louvered flat-type air door at each top of the two wind roadways based on traditional ventilation system of coal mine to keep constant of underground air flow in switchover process of ventilators.The actual application validated feasibility and practicality of the scheme.
