摘　　要：义棠矿井在冬天出现主斜井风流方向反向,给矿井通风系统稳定带来安全隐患。首先通过理论计算和实际测量,然后找出原因主要是外界天气气温的突然降低和行人井暖风风量的增大,最后通过调节暖风风量和增设巷道局部风阻使风流方向恢复正常。In the winter,the direction of the main shaft in the main shaft is reversed,which brings the safety hazard tothe stability of the mine ventilation system.Through the theoretical calculation and the actual measurement,the mainreason is found,which is the sudden decrease of the external weather temperature and the increase of the air flow rateof the pedestrian well.By adjusting the amount of warm air and additional roadway local wind resistance,the directionof the air flow is ultimately back to normal.
