| Abstract: | Based on field observation,theory analysis and digital simulation,the authors present the rules of mining pressure manifestation of roadway along the mined area in deep mine sublevel caving longwall face.According to the analysis of compound strata of roadway,the authors get the surrounding rock structure and geometrical structure of roadway which is along the mined area.Finally this paper presents the control methods of surrounding rock under different stress distribution and plastic zones. |
