Abstract
The stress of surrounding rock at roadway intersection is complex. U-shaped steel support has been used at the roadway intersection of Yanghui Mine in Vietnam, but there are many problems, such as blocked ventilation and limited passing capacity. In this paper, FLAC3D numerical simulation software is used to simulate the support effect of U-shaped steel and bolt based on the field data of Yanghui Mine. The deformation of roof, floor and two sides are compared. The results show that the bolt support can be applied to the intersection of roadways in the mine to improve the support of the mine.
