摘　　要：针对作业面柴油、电气设备产热量大,局部地点湿球温度超限,局部通风机选型困难的问题,以某地下金属矿山3个作业面为原型,通过Ventsim矿井通风系统三维仿真模拟,开展点热源产热及不同局部通风方式下温度变化规律研究。通过对作业面进行压入式、抽出式、混合式局部通风仿真模拟,对比作业面降温效果,对该矿作业面局部通风机选型、风筒布置类型进行设计。结果表明:该矿山井下3个作业面风机型号应为JK40-1No.8,风筒规格为800 mm,局部通风方式为长压短抽混合式,共需6台局扇和6道风筒配合使用。研究结果可为地下矿山作业面局部通风设计提供技术指导。Aiming at the problems of large heat production of diesel equipment and electrical equip-ment in the working face,excessive wet bulb temperature in local places,and difficult selection of local ventilators,taking three working faces of an underground metal mine as the prototype,the three-dimension-al simulation of Ventsim mine ventilation system is carried out to study the heat generation of point heat source and the temperature variation law under different local ventilation modes.Through the simulation of press-in,pull-out and hybrid local ventilation on the working surface,the cooling effect of the working sur-face is compared,and the selection of the local fan and the arrangement type of the air duct on the working surface of the mine are designed.The results show that the fan model of the three working faces in the mine should be JK40-1 No.8,the specification of the air duct is 800 mm,the local ventilation mode is long-pres-sure short-pumping hybrid ventilation,and a total of 6 local fans and 6 air ducts are required.The research results can provide technical guidance for local ventilation design of underground mine working face.
