Analysis and Three-Dimensional Simulation on Stability of the Rock Surrounding in Mined-out Area Based on Block Theory

摘要：

The block theory of discount deformation method is introduced. Based on the project background that is the transport opening of gold mine, the key block and the maximum movable district of the rock surrounding are defined by the block theory, BST and UNWEDGE methods. By the application of block theory on the stability, the factors influencing the rock surrounding stability and the Fs of the key block are analyzed. For the rock surrounding is instability, so the grouting and bolting methods is used to supporting the collapsing. The 3DEC method is use to verify the effect of supporting method.
