| Abstract: | The geological structure of Jingerquan copper - nickel deposit in Xinjiang is special,roadway excavation must break through weak and broken layer. In this paper,the causes of soft rock roadway damage and the failure mechanism of weak and unstable structure are analyzed,then,combining with the support features for soft rock roadway and its support principle,as well as the characteristics of roadway construction in the mine at the present stage,some support schemes of roadway in weak and broken zone are presented. |

| Keywords: | Soft rock roadway Faulted structure Failure mechanism Advance supporting Bolt support |
