下行通风在矿井高温治理中的应用

Application of Downward Ventilation in High-temperature Treatment in Coal Mine

针对东坑仔煤矿西井田独立块段高温问题,采取了优化通风系统,改革通风方式,及变采区上行通风为下行通风的方案,甩开了边界末端不良进风流,取到了良好的降温效果;改变了原有高温高湿的作业环境,对降低工人劳动强度、稳定职工队伍、促进安全管理,起到了积极的作用。

Aimming the high - temperature problem at the independent segment in west mine of Dongkengzi Coal Mine, ptimization of ventilation system was adopted, the ventilation way was improved, the upward ventilation was ehanged into downward ventilation, the bad wind at the border end was thrown off. The good effect of redueing temperature was obtained. The original work environment was improved. It played an active role for reducing the labor intensity of workers, stable workforce, and the promotion of safe management.
