Abstract: In view of the difficulties encountered in the use of the key technologies in the mining face by drawing and filling, this
paper used FLAC3D numerical simulation software to analyze the deformation of the roadway under different stagger distances and
the deformation of the roadway with or without support, and obtained the effective support to reduce the deformation of the roadway
within the reasonable stagger distance, which provides a guarantee for the safety of production.
