Abstract: In order to realize the rapid mining of the fully mechanized mining face of Xiegou Coal Mine, the scheme of preexcavating
single retraction channel was adopted. Aiming at the stability problem of the large deformation of the retraction
channel, on the basis of the traditional stacking support technology, hydraulic support was used to strengthen the support. This
paper studied the application of hydraulic support technology in the retraction channel of fully mechanized mining face. The
results show that after adopting the hydraulic support technology, the moving amount of the roof and floor of the retraction channel
was reduced, the phenomenon of heaving floor was also greatly reduced, the cost was saved by 9.89×10⁵ yuan, and the retraction
time was reduced by about 25 d.
