Research on the Transition Section Length of the Mixed Workface Using Gangue Backfilling Method and Caving Method

Aiming at the problem of the sudden increase of the working resistance of the support in the transition section of the mixed workface, this paper adopts the physical simulation to study the fracture and movement characteristics of the overburden strata in the backfilling section and the caving secti...
