摘　　要：主要阐述了ZLD-1500型煤矿井下用氮气冷却机组的低温冷却机组、构成、典型优点及性能参数,并基于矿用制氮装置(氮气流量1500 m^(3)/h、氮气出口压力1.0 MPa)工况下,对煤矿井下用氮气冷却机组的氮气出口压力、氮气出口温度及各项安全保护进行了测试。测试结果表明,机组在氮气流量为1500 m^(3)/h的工况下,氮气出口温度可以达到-30℃,满足现场需求,为采空区自然发火的防治提供了一种行之有效的手段。The low-temperature cooling unit,composition,typical advantages,and performance parameters of the ZLD-1500 Coal Mine underground nitrogen cooling unit were mainly elaborated.Based on the working conditions of the mining nitrogen production device(nitrogen flow rate of 1500 m^(3)/h,nitrogen outlet pressure of 1.0 MPa),the nitrogen outlet pressure,nitrogen outlet temperature,and various safety protections of the coal mine underground nitrogen cooling unit were tested.The test results show that the unit operates at a nitrogen flow rate of 1500 m^(3)/h,the nitrogen outlet temperature can reach-30℃,which meets the on-site demand and provides an effective means for the prevention and control of spontaneous combustion in goaf.
