摘　　要：在煤矿开采中,受到井下恶劣环境的干扰,需要做好通风工作,预防瓦斯超限等事故发生。为此,以A煤矿井下作业为例,基于对主采作业面地质的了解,从采煤面、掘进面、硐室、备用工作面、其他用风巷道等用风地点出发,进行需风量的计算。结合实际通风情况,展开通风能力的核定,得出进风量监测数值大于需风量计算值,可以满足矿采用风需要。最后进行风量计算的验证,得出各地点风量满足《煤矿安全规程》的有关规定。In coal mining,due to the interference of harsh underground environment,ventilation work needs to be done well to prevent accidents such as gas exceeding the limit.For this reason,taking the underground operation of A Coal Mine as an example,based on the understanding of the geology of the main mining face,the required air volume was calculated from the coal mining face,driving face,tunnel,backup working face,other ventilation tunnels and other ventilation locations.Based on the actual ventilation situation,the assessment of ventilation capacity was carried out,and it was concluded that the monitoring value of the intake air volume was greater than the calculated value of the required air volume,which can meet the wind demand of the mine.Finally,the verification of air volume calculation was carried out,and it was found that the air volume at each location met the relevant provisions of Coal Mine Safety Regulations.
