瓦斯爆炸会给煤矿生产带来严重的灾害和人员伤亡，但目前瓦斯爆炸的影响研究主要集中在单一爆炸源上，瓦斯爆炸的缺乏瓦斯爆炸与单一爆炸源不同。 并模拟了双爆源气体爆炸作用下冲击波在巷道中的传播特性和围岩损伤规律，确定了巷道内激流场、轴压变化和冲击波的动力响应，研究结果表明，当巷道内双爆源气体爆炸发生球形扩散时， 然后与围岩相互作用，然后以不规则电弧向两端传播，直到与合成波另一侧的冲击波碰撞不断扩散，两个冲击波的碰撞叠加不是简单的线性叠加;通过观察巷道中对称断面的墙体响应，并比较巷道中单爆源气体爆炸的墙体响应，可以看出，在双爆源气体爆炸的道路安全设计和单爆源气体爆炸的安全设计中应注意对拐角和屋面的保护， 但与单一爆源气体相比，防爆应更加注意护角。
