Abstract EN
The study and accurate prediction of the movement of overburden rock mass and surface subsidence are crucial for a safe production in metal mines.
This study investigates the relationship between the movement laws of overlaying strata and the time space of a mined-out volume using Rock Failure Process Analysis (RFPA) System.
Furthermore, the movement, deformation, and failure laws of overlaying strata are examined in different positions when a goaf volume is certain and the failure behavior of the overlaying strata.
This study analyzes the similarities and differences of the overlaying strata comparatively.
Results show that, regardless of the movement range or subsidence value of the overlying rock mass, a power function relationship is observed between them and working face advancement.
Setting the equation shows that the scope of the overlying rock mass is significant when the ratio of a certain position distance roof to the working face distance is small.
The results provide a reference for controlling the displacement of the overlying rock mass and treating goaf.
