@@@@Aiming at field conditions of gob-side entry retaining of working surface back production of an large-scale mine, the author built mechanical model of gob-side entry retaining, and designed analysis effect of roadside support by using plate mechanics theory and methods of combining theory analysis and site test. Finally, the author researched relationship between surrounding rock structure model of gob-side entry retaining and support pressure.
