Abstract: In order to improve the driving speed of the large section roadway under complicated geological conditions, four influence factors are got with factor analysis in Jinzhuang Company, including engineering geological conditions, excavating equipment, supporting technology and construction technology, construction organizing and management. Through numerical calculation of different support scheme with FLAC3D,better supporting technology and construction technology are proposed. Field application shows that, optimization scheme significantly improves the speed and reliability of roadway support, laying the foundation for fist working face.

Key words: large section roadway, rapid excavation, influence factor, technology optimization
