摘要
针对新二甲二号隧道具有瓦斯突出的煤层这一现状 ,介绍了施工过程中采用的瓦斯监测超前钻孔探测 ,浅眼多循环控制爆破 ,加强支护等技术 ,指出要保证安全生产 ,必须搞好瓦斯监测。
According to the gas outburst coal bed in 2# tunnel methane monitoring advanced drilling detection and short-hole controlled blasting are adopted in the construction to intensify supporting. In order to ensure the safety in construction the gas detection must be done well.
