Abstract: In view of the difficult roadway retained and serious deformation problems at large mining height working face, In this article, using 5310 large mining height workface in Chengzhuang Coal Mine of the Jincheng Coal Group as engineering background, the anchor rope-steel ladder reinforcing measure was used to carry on parameter design for advancing secondary support, and monitored the roadway deformation. Monitoring results showed that the support effect is remarkable and roof subsidence was 70 mm, the largest amount of floor heave was 210 mm, the deformation of two-wall is 120 mm, which was 8.4%、46.2% and 13.9% of not reinforcing roadway, the effect has reached the expected requirements.
