Abstract: Using numerical simulation software, based on Mohr-Coulumb and strain softening models, the specific parameters of
the filling body were determined. Under the parameters of the filling width of 1.2 m and the water-cement ratio of 1.5颐1, the
surrounding rock can be effectively controlled. The actual engineering application results showed that under this filling scheme,
the maximum displacement of the roof was 315 mm, which solved the problem of large deformation of the surrounding rock caused
by the collapse of the hard roof.

Key words: numerical simulation; filling; hard roof collapse
