Abstract: According to investigation of permanent roadways, the Y-shape intersection is main form of No.2mine area in Jinchuan mine. For roadway intersection, many factors have influenced stability of roadway, sequence excavation is fallen into this category. A finite element software is utilized to simulate Y-shape roadway intersection in No.2mine area in Jinchuan, and analyzed stress and displacement influenced by different excavation sequences. There are two types of excavation sequences:type one:main roadway-branch roadway; type two:main roadway-branch roadway-main roadway. The results showed as follows:the displacement of intersection roadway by type-two sequence is bigger than displacement intersection roadway by type-one sequence. Branch roadway excavation leaded to value difference in both sides of roadway. As displacement increased, the stresses of roadway have been offset. This features provided some reference for roadway support. Finally, Y-shaped intersection excavation should first choose type-one sequence for stable. Appropriate support should be used in roadway intersection excavated by type-two.
