Study on full coupling analysis method for stability of underground roadway engineering
The paper put forward Full Coupling Analysis method and optimization design idea to the stability problem of underground roadway engineering,based on Rock Engineering System (RES) theory.At first,Full Coupling Analysis method and technique path briefly interpreted in the paper,and twenty-seven rock litho logy swatches collected.Global interaction matrix of roadway had been made up by artificial network coding method,and the main influence factor and effect mechanism had been analyzed.And then stability value parameters were put forward from stabilization capability analysis result of roadway engineering system,and capability state ranges gave.At last,Shaqu Coal Mine acted as an example to stabilize analysis and supporting optimization design,coupling supporting system which is made up of cable and bolt firstly was put forward.The results of analysis and local datum indicated that the mechanical character of surrounding rock mass be optimized improved,and the ki of roadway engineering system is 1.03.So the roadway lies in middling steady,Observed datum indicated the relative sinking velocity of roof less than 0.2～0.5 mm/d.it meets production need by and large.So the Full Coupling Analysis method had practicality value to stabilization analysis and supporting design.
