The quantity of coal and gas outburst energy in the hole and the influence factor and action of shock-wave pressure difference in tunnel after outburst were analyzed to reduce impairment. The shock-wave pressure difference of per ton energy in tunnel after outburst was analyzed quantitatively the thickness of coal, the interaction of the quantity of outburst energy and the shock-wave pressure difference, so as to reference.%从诱发煤与瓦斯突出的根源入手，分析了水力掏槽槽硐中突出能量、突出后巷道中冲击波压力差的影响因素及作用，通过突出能量、冲击波压力差作用关系，定量分析突出后吨煤能量在巷道中产生的冲击波压力差，以供参考。
