摘要
为了解决赵楼煤矿5302采煤工作面因其宽度较大、顺槽过长所导致的面内严重热害问题,根据煤矿现场实际情况,对面内热害形成规律、热湿源分布等进行了系统研究。提出了针对超长采煤工作面降温方法,即"空冷器+防尘水+乳化液"组合降温技术。新的降温技术运行以来,通风路线上的温度保持在20℃~30℃,降温效果明显。
In order to solve the problem of serious heat ~amage causeu Dy lal$~ ~ crossheading in the surface of coal mining face of Zhaolou coal mine, according to the actual situation of the coal mine, studies the formation of heat damage in the opposite area, the distribution of hot and humid source, etc. A cooling method is proposed for the coohng of the super-long coal face - ＂air cooler ＋ dustproof water ＋ emulsion＂ combination cooling technology. Since the new cooling technology has been running, the temperature on the ventilation line is kept between 20 % and 50 ℃, and the cooling effect is obvious.
