| Abstract: | Aiming at the serious surrounding rock deformation of the roadway under the original support design of the transportation gateway in the fully mechanized top coal caving working face,the surrounding rock deformation of the roadway is controlled by adopting the measures of densifying support and optimizing support parameters.The approach of the two sides is stable at 270 mm,the approach of the roof and floor is stable at 205 mm,and the support effect is good. |
