大断面岩巷快速掘进技术研究

Research on Rapid Excavation Technology of large section rock roadway

随着煤矿机械化的发展,井下主要运输巷道的断面尺寸越来越大,采用传统的巷道掘进方法不但掘进速度慢而且消耗的人工也很大。通过在内蒙古新上海一号煤矿一水平北翼轨道运输大巷施工实践探索,总结了部分加快大断面岩巷快速掘进的方法。

With the development of mechanization of coal mine, the section size of the main transport roadway islarger and larger, the traditional roadway driving method is not only slow speed but also the consumption of labor isvery large. Based on the practice and exploration of the construction practice of one level north wing rail transportof new Shanghai No. 1 coal mine in Inner Mongolia, the author summarized some methods to accelerate the rapidexcavation of large section rock roadway.
