云台山瓦斯隧道揭煤爆破及安全技术研究

Study on the Explosion and Safety Technology for Coal Uncovering in Gas Tunnels in Yuntai Mountains

研究了侯月线云台山瓦斯隧道平导第一次揭煤爆破设计的主要爆破参数以及实施的安全技术措施，据此顺利安全地完成了平导与主洞的２２次揭煤，为类似情况下的瓦斯隧道施工提供了揭煤以及瓦斯管理等方面的宝贵经验．

An account of the main explosion parameters and the safety technology and measures used in the first explosion design to uncover the layers of coal in the auxiliary adit of the tunnels with gas in Yantai Mountains on the Hou_yue railway is given. These parameters, technology and measures assured the smooth and safe completion of coal uncovering which were repeated for 22 times in both auxiliary adit and the main tunnel. Thus, valuable experiences can be drawn there and used for the similar cases involved in the construction of tunnels with gas.
