摘　　要：为了防止采取降温措施后回采工作面内产生上下冷热分布不均问题(进出风口温差过大),提出回采工作面内风筒均匀供冷方式,即在工作面进风巷道内安设风机和降温系统末端散冷设备(空冷器或蒸发器),其后接一定长度的风筒,风筒上根据工作面长度等距开设出风口,在工作面内利用风筒及所开设的出风口均匀输送冷风.以此为基础,阐述了风筒均匀供冷基本原理和形式,并以某工作面为例对具体操作工艺进行了分析.可以缓解采取降温措施后工作面冷热分布不均的问题,又能够尽最大程度的不影响工作面正常生产,比较符合现场工程实际.In order to prevent the cold capacity maldistribution phenomenon( or excessive temperature difference between intake and return air) in coal mining face,the method of duct uniform air supply at the coal face is proposed in this paper. This method needs to install the fan and air cooler at intake air way. Following the air cooler is a certain length of duct with equidistant ventilation holes on it. All of these help to ensure the same quantity air that can be delivered to the face. Based on this method,the basic principle and the layout of uniform air supply have been conducted. At last,the concrete operation technology is analyzed under a certain coal face condition. This method can not only relieve the maldistribution of heat and after being cooled,but also hardly affect the regular production to the greatest extent,easily complying with the engineering practice.
