| Abstract: | In order to alleviate the tension of mining replacement,improve the coal recovery rate and reduce the amount of roadway excavation,the high water filling material along the goaf retaining technology is used in the material roadway of the lower face 1204.The deformation of the roof,floor and the surrounding rock of the roadway side is stable at 78mm and 94mm,and the deformation of the surrounding rock of the roadway is effectively controlled to ensure the safe use of the roadway. |
