摘　　要：为消除冬季地下矿山回风井井口雾气对周边居民区造成的心理影响,依托云南某铅锌矿通风优化项目,通过现场检测,得到不同工况条件下空气含湿量差值以及成雾析出水量,并依据部分相似原理建立除雾几何模型,对不同工况条件下除雾效率进行了试验对比。试验得出当环境温度为-1℃左右,压降值小于等于189Pa,风速达到4.5m/s时,除雾效率达到最佳,为96.3%,试验结果为矿山井口除雾工艺的研究提供了依据。To eliminate the psychological impact of the surrounding residential areas caused by the wellhead mist in return air shaft of underground mine in winter,relying on a certain lead-zinc mine ventilation optimization project in Yunnan province,field tests were carried out to obtain the air moisture content difference,as well as the fog and water separation under different working conditions.A fog geometric model was built according to some similar theories to compare defogging efficiency under different working conditions.The test results show that when the ambient temperature is about-1℃,the pressure drop value is less than or equal to 189Pa,the wind speed reaches 4.5m/s,and the defogging efficiency reaches the best of 96.3%.The research results can provide a certain basis for the study of defogging process in mine wellhead.
