摘　　要：基于冬瓜山铜矿新区(冬瓜山矿段)通风系统采用多级机站通风方式,多级机站通风系统反风不能简单盲目地直接使风机反转反风。根据冬瓜山矿段井下通风系统现状,将通风系统区域划分为进风区域以及采区靠近进风侧区域、回风区域以及采区靠近回风侧区域,针对各可能的着火区域,借助建立的通风远程监控系统平台,采用分区域、分级控制技术,通过机站风机的开停、反转等优化组合方式进行风量风压的调控,以有效地调控火灾烟流方向,提高抗矿井火灾突变能力。Multistage fan stations ventilation was used in the new area （Dongguashan ore section） of Dongguashan Copper Mine, and fan can not be run back simply and directly to reverse airflow. According to the present situation of underground ventilation system of Dongguashan ore section, the ventilation system was divided to the air inlet side, mining area near the air inlet, the return air area and mining area close to the return air. For each possible fire area, establishing the long-range monitoring system platform of ventilation, and using the regional and stepping control technology controlled the air-quantity and air-pressure through starting and stopping the fan and fan reversing so as to effectively control the smoke flow direction, and improve the fight ability against mine fire.
