长距离采煤工作面降温方式优选研究

Study on Optimum Selection of Cooling Method in Long-distance Coal Mining Face

以5302长距离工作面为工程背景,对局部降温原理进行分析,并对比了空气冷却降温方式,防尘水以及空气冷降温相结合方式,防尘水、空气冷降温以及乳化液组合降温方式等三种方案,布置方式以及制冷效果,综合确定,防尘水、空气冷降温以及乳化液组合降温方式更优,能够满足5302长距离工作面的降温需要。

Taking 5302 long-distance working face as engineering background,this paper analyses the principle of local cooling,and compares three schemes,that is air cooling method,combination of dust-proof water and air cooling method,combination of dust-proof water,air and dust-proof water and air cooling method.The layout and refrigeration effect are synthetically determined.The effect of combination of dust-proof water,air and dust-proof water and air cooling method is better,and can meet the cooling needs of 5302 long-distance working face.
