Abstract

Pointing to the problem of stability control of coal roadways supported by rock bolts,based on the coordinate deformation condition of rock bolting system,the principle of dynamic monitoring and feedback of surrounding rocks was given,and its quota chosen and determined and its application codes were analyzed.The application effects of engineering monitoring and feedback are expounded through examples.
- coal roadways,
- rock bolt supporting,
- abscission layer critical value,
- monitoring and feedback
