摘　　要：复杂地质构造、高瓦斯、易燃煤层条件下,工作面初采初放期间瓦斯安全管理,是实现安全生产的关键。通过调整采区通风系统、高位钻孔抽采采空区瓦斯、工作面下隅角埋管、架间插管抽采瓦斯、安全监测监控等措施,使工作面初采初放期间及下行通风段安全回采,实现了瓦斯安全管理。Safety control of working face during the initial mining and blasting down the roof is the key to guarantee safety production under the condition of complicated geological structure,high gassy,spontaneous seam.Though the following measures,adjusting ventilation system at working face,extracting gas from gob area by high drilling,laying pipes under the lower corner,inserting the pipes among the holder,monitoring the safety,we achieve the safety mining at working face during initial mining and discharging and at downward ventilation section,and gas safety management.
