平顶山一矿丁十采区是下山煤,随着开采深度增加,带来通风困难,采面温度增高。夏季七、八月份,工作面气温高达31℃,不仅恶化劳动条件,而且影响职工健康。通修队职工在局矿党委的领导下,通过“三结合”小组调查研究之后,大胆使用下行风来降低工作面气温。通过一年多的实践,实现了用下行通风。下行风是有效降低工作面气温的技术革新,并使煤尘减少,改善劳动环境,深受广大工人欢迎。 Pingdingshan Ding 10 mining area is down coal, with the mining depth increases, bringing ventilation difficulties, mining surface temperature increases. Summer in July and August, the face temperature up to 31 ℃, not only worsened working conditions, but also affect the health of workers. Through the investigation and study conducted by the “Three Combinations” group, the workers in the overhauled team, under the leadership of the Bureau and Party Committee, boldly used the downward trend to reduce the face temperature. Through more than a year of practice, to achieve the use of downlink ventilation. The downside wind is an effective technological innovation to reduce the working face temperature, reduce coal dust and improve the working environment, and are favored by the workers.
