摘　　要：针对现有采煤工作面冷损大、冷量利用率低,提出一种新型的工作面降温系统;阐述了工作面冷量回收的原理;并对新型降温系统进行了详细介绍,根据某矿采煤工作面具体情况,对不同进水温度下,3个临界条件小型空冷器的风流进行模拟,对比其降温效果,结果表明:降温效果同样明显。从而验证了采煤工作面冷量回收的可行性。Aiming at the low cooling capacity and low utilization rate of coal mining face, a new type ofworking face cooling system is put forward; the principle of cold recovery in working face is expounded;and the new cooling system is introduced in detail. According to a mine the results show that the effectof cooling is also obvious. The results show that the cooling effect is also obvious. The results show thatthe cooling effect is similar to that of the small air cooler. Which verifies the feasibility of cold recoveryin coal mining face.
