摘要
结合龙溪隧道工程概况及围岩情况,确定了隧道开挖及揭煤方案,从瓦斯释放、通风、瓦斯监控三方面介绍了高瓦斯情况下,隧道施工采取的防瓦斯突出措施,并提出了施工注意事项,以有效防止瓦斯事故的发生。
Combined with engineering situations and surrounding rock conditions of Longxi tunnel excavation scheme is determined. From three aspects： gas drainage, ventilation and gas monitoring measures to prevent gas outburst are proposed for tunnel construction. Matters deserving attention are pointed out to prevent gas accident.
