摘　　要：为了量化采煤工作面非均匀环境营建技术气流组织,提高采煤工作面降温效果,利用热平衡方程、射流理论,研究了追踪型小型空冷器降温范围、数量、送风量、送风速度、射流角度,对2301采煤工作面进行了工程计算,采用皮温测试和主观热感觉的方法进行了热舒适试验研究。结果表明：2301工作面均匀布置10个小型空冷器,每个风量0.46 m3/s,射流出口风速2.34 m/s,射流末端风速0.54 m/s,符合工作面风速要求;受试人员各测点平均皮温在32.16-33.82℃之间浮动,皮温平均值为33.05℃,结果与Fanger舒适皮温接近,工人热感测试认为舒适的占65.7%,认为稍暖的占23.6%。In order to obtain the air distribution equation of non-homogeneous environment establishment technique in coal face to improve cooling effect,the cooling range,quantity,supply air volume,air velocity,jet angle of the tracking small air cooler were studied by using heat balance equation and jet theory.The engineering calculation and thermal comfort experiment using methods of skin temperature test and subjective thermal feeling for 2301 coal face are researched.The studies show that 10 small air coolers are arranged uniformly and supply air volume is 0.46 m3/ s of each cooler; outlet and end air velocity are 2.34 m / s and 0.54 m / s which accords with the requirement of wind speed.The average skin temperature of each measuring point changes from 32.16 ℃ to 33.82 ℃; average value is 33.05 ℃ closing to Fanger comfortable skin temperature.The number of workers thinking comfortable and a bit warm account for65.7% and 23.6% in thermal test.
