摘　　要：采用突出煤和阻挡层组成的延期突出模型,对延期突出事故的认定进行了探讨。结果表明,打钻、手镐、清煤(或矸石)、维修巷道、支护等作业过程中发生的突出应归类为延期突出,突出发生前无作业条件下发生的突出也属于延期突出。2007年至2016年间,延期突出次数占煤与瓦斯突出总次数的比例为19%,延期时间最短的为42 min,打钻过程中延期突出发生次数最多。Identification of coal and delay outburst accident is discussed based on the combination model of outburst-prone coal and barrier layer. Results show that if an outburst accident occurs during operation of drilling, picking, clearing of broken coal or gangue, roadway maintenance, roof support, as well as no operation before the occurrence, it should be considered as a delay one.From 2007 to 2016, the number of delayed outburst accounts for 19% of the total number of coal and gas outburst, and the shortest delay time is 42 minutes. The number of delay outburst accidents which take place during drilling operation is the biggest one.
