Based on rock engineering system (RES) theory

a full coupling analysis method and optimization design idea for the stability problem of underground roadway engineering are put forward. At first

the full coupling analysis method and flow are described briefly; and then collecting twenty-seven lithology samples. Global interaction matrix （GIM）of roadway had been made up by artificial network coding method; and the main influential factors and effect mechanisms had been analyzed. And then the stability evaluation parameters are proposed from the results of stabilization capability analysis; and the stability state ranges are given. At last

taking Shaqu Coal Mine for example

stabilization analysis and supporting optimization design are made; and the Q system is applied to appraise rock body quality for contrast analyze and validate the design result. All the results show that the full coupling analysis method has practical value for stability analysis and supporting design.
