Abstract: Based on 40110 fully mechanized caving face haulage of a certain mine in Binchang Mining Area, the support scheme in the process of excavation is optimized. This paper applies FLAC numerical simulation software to establish the corresponding calculation model, comparatively analyzes the deformation law of surrounding rock before and after the support design optimization. Industrial test and monitoring research show that the support optimization scheme of haulage is reasonable and feasible, which ensures the stability of surrounding rock.
