摘　　要：为了解决矿井采掘接替困难、1602运输巷掘进速度缓慢的问题,实现安全、快速消突,研究提出了致裂快速消突技术。在1602运输巷进行区域防突措施瓦斯抽放期间,当抽放管路中瓦斯浓度下降到2.8%时,通过施行致裂快速消突技术,抽放钻孔的平均瓦斯浓度最大增加了5.5倍,平均增加了3.2倍,抽放时间缩短了25d,实现了安全、快速消突的目标。In order to solve the problems of difficult replacement of mining and slow driving speed of 1602 transport roadway,and to achieve safe and rapid outburst elimination,the technology of rapid outburst elimination by cracking was studied and put forward.During the gas drainage of regional outburst prevention measures in 1602 transport roadway,when the gas concentration in the drainage pipeline drops to 2.8%,the average gas concentration in the drainage borehole increases by 5.5 times,3.2 times,and the drainage time shortens by 25 days,thus achieving the goal of safe and rapid outburst elimination.
