Study on stability of filling wall under lateral large-span composite hinge fracture of hard critical block

There is still a lack of mature researches on the stability mechanism, influencing factors and control technology of the gob-side filling wall, and systematic researches on the cracking forms and characteristics of the stope roof and the stability of the filling wall are rather insufficient. This pa...
