| Abstract: | There are some problems on the support of shotcreting and bloting mesh for deep weak rock roadway in No.1 Mine of Shizuishan.Based on experiment of physical and mechanical characters and analysis of minerals composition of weak rocks,and destroy condition of roadway,analyzed the reason for deformation and failure of surrounding rocks from some aspects on arrangement of roadway,design of support,properties of surrounding rocks,management of construction and so on,and provided suggestions of controlling surrounding rocks of roadway stability,which has a certain reference value of practicing to support roadway. |
