韦家沟煤矿降温技术研究与应用

Research and application of cooling technology in Weijiagou colliery

对韦家沟煤矿热害进行了研究,提出了冷水机组的矿井降温系统设计方案,降温7.4℃,降温效果显著。在空冷器距离掘进工作面一定范围内,均可达到预期的降温目标。既提高了劳动生成效率,又避免由于环境温度过高而造成安全生产事故。

After the study on thermal damage in Weijiagou colliery, the design scheme of mine cooling system with chillers was proposed. The temperature dropped by 7.4 ℃, the cooling effects were remarkable. Expected temperature drop reached within the distance from the air cooler to the tunneling face. Thus, the productivity enhanced, and safety accidents caused by high ambient temperature were avoided.
