【摘要】：针对矿井采掘工作面的高温现象,结合矿井采掘方式和采煤工艺过程,分析了矿井产生热害的原因,提出了新型移动式井下局部降温技术,介绍了TS-300B型移动式局部制冷降温系统工作原理,即利用井下巷道的冷却空气,通过制冷、压缩以及冷凝等措施将热量传递给冷却水,并通过通风机将冷风吹向工作面,冷热交换不断循环,从而达到降低采掘进工作面高温。通过在郑州李粮店煤矿的应用实践表明,根据检测现场降温前后的参数比较,该移动式井下局部降温技术降温效果明显,采掘工作面的温度可降低至26℃左右,相对湿度也相应降低了10%~20%,有利于消除矿井热害,符合井下安全生产的要求。
[Abstract]:In view of the high temperature phenomenon in mine mining face, combined with mine mining mode and coal mining process, this paper analyzes on the causes of thermal damage in mine, puts forward a new type of mobile underground local cooling technology, and introduces the working principle of TS- 300B mobile local refrigeration cooling system, that is, the heat is transferred to cooling water by means of cooling air in underground roadway, such as refrigeration, compression and condensation, etc. Through the ventilator, the cold air is blown to the working face, and the cold and heat exchange is constantly circulating, so as to reduce the high temperature of the mining face. The application practice in Liliangdian Coal Mine of Zhengzhou shows that according to the parameters before and after the detection site cooling, the cooling effect of the mobile underground local cooling technology is obvious, the temperature of the mining face can be reduced to about 26 鈩，
