Abstract: Research was made on the effect of fracture structure on laneway stability.Based on the site detailed sketch map plotting of the fracture structure, the laneway destruction forms were classified and summarized.Mechanical analysis was made on the laneway existence time and the fracture structure where the surrounding ore-rock lies to find out the relation between the fracture structure and laneway stability.As a result, the destruction effect of the fracture structure on laneway can be scientifically predicted and forecasted so that rational driving method and necessary support form can be adopted for ensuring a safe production and full recovery of mineral resource.

Key words: Fracture structure, Laneway, Stability, Safety
