[Abstract] 
Key Conclusions:
fiogf49gjkf0d
The system achieved the monitoring data fusion of surrounding rock displacement, stress and deformation and visual analysis, it carried out warning and forecasting for the safety hazard of coal mine surrounding rock power.
Key Findings:
fiogf49gjkf0d
The model was loaded by hydraulic cylinder, stimulating the in-situ rock stress field and the induced stress field of surrounding rock. the deformation monitoring system of roadway was constituted by optical total stations, borehole observation instrument, acoustic emission monitoring, stress sensors and so on, we got a wealth of data through an omni observation of surface displacement, characteristics of stress distribution, and deformation and failure of surrounding rock masses. By acoustic-optic-electric methods, a real-time testing on physical, mechanical, damage parameters was realized through the experimental process.
Objective of the Paper:
fiogf49gjkf0d
Study the surrounding rock deformation and failure mechanisms in three-dimensional stress state.
Problem Statement:
fiogf49gjkf0d
Roadway deformation and stress migration occurred by tunneling and mining influence. Its behavior with uncertainty and randomness.
